Wallap Retaining wall in sandy soil
Hi All,
I'm recreating the example 1 in the paper by Burlund and Potts(1981).
Please let me know if you have any problems.
Thank you.

My name is Chathurika Jayasundara, and I am a PhD student in the Civil Engineering Department, Monash University. This is my video entry for the Monash Global Discovery Program, New York City, 2019. #monashdiscovery #monashalumini #monashuni
Thanks, Chathurika, for the informative video
`FENERBAHCE` headline is on the view result page :)
This program is terribly primitive and fails to take into account the nonlinear, nonelastic, deformation characteristics of soil materials as a function of effective stress.
Great content 👌👌 Quick one, how did you calculate bending moments ?
From the model. See the results.
Great content. Thanks for your time. cheers
hi , why you did not apply water pressure under 1.7 after dewatering ?
Hello, Thank you for the videos, your work is very helpful, can you make a video on resins using DEPVAR using umat. Thank you :)
Hello mam, Your video is very useful and your teaching method also good, Mam can you make a video on visco-elastic material in writing code in UMAT relating to temperature parameters involved in it. Thank you
Really useful tutorial. May I please know, is there any availble user guide or software manual for WAALP?
Hi! I do not think so. I also self-studied. Thanks.
Hi, how can I download Wallap? I need it for my thesis in University :( Thank you.
www.geosolve.co.uk/wallap1.htm? Hi, You will need a paid dongle. Thanks.
Could you please produce a video for WALLAP contiguous pile. Thank you
thank you for these videos. Im a senior geotechnical engineer in South Africa. They are very helpful
dear, I am modeling a marine slope with increased pore pressure in the abaqus using the Can-Clay model. I found the following error. " The sum of initial pressue and elastic tensile strength for the porous elastic material in element 1 instance ground1-1 must be positive." What was the solution you found to overcome the problem? Thanks and regards.
Hi can you make a software work of wallap for me . pls reply asap
Mam, I am doing simulations concerning cables. Abacus only showing up to elasticity. But I want it for elasticity. Can you please provide any reference for that. I want to capture after elasticity points with the help of subroutine with 1d elements ( strain hardening, necking, and rupture).
Can you please explain me. How to write a umat subroutine for 1d beam element for plasticity.
Please can you put the link of the software
www.geosolve.co.uk/wallap1.htm?
thanks for sharing chathurika for the tutorials. Its been very helpful. can you do one on using anchorage and seismic analysis for propped cantilever retaining wall
Was really helpful...Thanks for your efforts !
Please make a video of Wallap Tutorials for beginners Tq
Hi, Pls i'm working on abaqus umat subroutine and the job is getting completed but no display of outputs (i doubt that the error still in the .for subroutine file ) please Help me fix that

Dear Sir, Thanks for this video. I will be pleased if you can provide me with UAMP Subroutines. Takns in advance !!!
Hi, How to find area of deflection curve?
hi, can I ask, how do you start writing the UMAT unit code? did you import that from edit keywords on model selection?
thanks so much for the effort
Hi, i would like to ask you some questions if you dont mi nd i will be grateful if you give me your email or anything i can contact you with thank you
Hi Chathurika. This is a great video. Can this case be shared with me? My email is goonatrip2020@gmail.com. Thank you.
Hi Chathurika...The video is nice.... i have written a UMAT based on a FRP composite. But the abaqus software is returning output as problem in compilation. Can you pls help me in this regard?.... 2) Before writing the UMAT should we load the ABA_PARAM.INC file?.....so as to not face compilation errors...if yes how can we resolve it?... I have been spending hours on this, but iam not getting result except frustration...Kindly guide me through this please...
Nice video.. How can I assign two different material properties using umat code?
Can you make a video for soldier pile design with wooden planks? ASAP! It's urgent!!!!
The image is BLURR. !!!
ma'am, could I get your mail id ?
thank you very much mam for the video, it was very helpful. please i need your help for UMAT for czm fatigue of composite laminates. my email id is safder1303@gmail.com
Hello, Mam, Do you have any subroutine for the Modified cam Clay model?
Hi Mehtab, Yes. Please send me the email adress. I will share it with you. Best regards, Chathurika

Hi, Thank you for making this video. Is it possible to call 'GETVRM' function in sdvini subroutine? Thank you, Oscar
good job
Thank you
Thank you for this informative video. Would like to see a video on how to convert a UMAT to a VUMAT.
Hi Charitha! Sure. I will add a video soon. Thank you
Please cover both undrained and drained analysis (with GWT at top) in next video...by differentiating the input and output.
Hi Santhosh!! Sure. I will be uploading new video soon. Thank you.
@@chathurikajayasundara7804 Thank you.
Hi Mam, This is most informative video I have seen about UMAT. Thank You for this video. There one question: in XY data from ODB field output the position you have taken is unique nodal not integration point. What is the difference between the two? Thank You.
Hi Ravindra! Thank you for the comment. An integration point is one of the nodal values within an element. For example an eight node C3D8R continuum element has eight integration points, one at each corner of the element. Element nodal and unique nodal positions both involve reporting results at the nodes of the model; however, reporting of unique nodal values produces only a single value at each node, whereas reporting of element nodal values produces one value for each element that has a contribution at that node. Only unique nodal values are provided in the case of node-based variables such as displacement. For element-based variables such as stress, extrapolation and averaging must be carried out to obtain unique nodal values. Therefore, I was intersted in one single node having displacement, U1 and U2 variable. That is why selected unique nodel. Hope that I answered your question. Thank you.
Hi Mam, Your video is very useful. The mesh element size of your model is increasing towards right. Is there any specific reason for that? Can you upload a video on progressive damage in composite laminate if you are familiar with it?
Hi Ravindra! By changing the mesh size of the rigid body, the geometry of your object changes. So, it is expected to affects the results. You should decrease your mesh size (especially in the sharp parts and critical loading regions) to achieve a more accurate results. Generally, in finite element modelling the meshing size increases when it aparts from the loading point. www.comsol.com/multiphysics/mesh-refinement#:~:text=As%20these%20elements%20are%20made,the%20model%2C%20and%20the%20results. This link provides more details on meshing. Sorry, I'm not femiliar with progressive damage in composite laminate. Thank you.
Hi, Very good video. Good work. Can you please also show how to do a diaphragm wall design in wallap?
Hi! Sure. I will add one soon.

Can you share the download link for this software
Hi, The link is: www.geosolve.co.uk/index.htm However, it is not a free software. You need to buy the license. Thank you.
Pretty amazing tips 👌
Glad you like them!
Dear Chathurika Thanks for useful video, please tell me how to add a new concrete material definition in abaqus; ? thanks
Hi Amr! I will be expanding the same code for soils soon. You will be able to repear the same for your concrete materail. More details: abaqus-docs.mit.edu/2017/English/SIMACAESUBRefMap/simasub-c-umat.htm Thank you.
