Wonderful video, thanks brother
Always welcome dear.
Hello, I need your urgent help. I am also a mechanical engineer and a PhD student in the field of biomechanics. My question to you is that you have mouse micro CT images. I created these bones in the 3D slicer and then transferred them to Meshimixer. I want to preserve the trabecular and cortical parts of these bones. Do I have to use Hypermesh for the analysis process in Abaqus? Isn't there a direct transfer from Meshimixer to ABAQUSA? Should I use Hypermesh? Are there other options? Thank you in advance.
Can we force hyperworks to generate hexa-dominant mesh (instead tetrahedral element), using same stl file generated from meshmixer?
Hello, I have been working on the L3-L4 region of the spine and everytime I use the meshmixer to smooth my model. After which when I import it to hypermesh, the model is error free, but when i mask and remove some portion of the model, it turns out to be hollow from inside. Could you help me with this issue, please? I have been stuck since a long time over this.
Dear,
Provide some visuals on my whatsapp or telegram.
Excellent video Dear Instructor,
Thanks for sharing your knowledge.
I have a question for you. After importing the mesh in Abaqus according to the methodology you proposed, Abaqus tell me that there is no geometry. So I have an Orphan Mesh. Can you provide me some suggestions to manage this problem? Can I export geometry from Hypermes and import it into Abaqus? Is it worth trying to import also the geometry in Abaqus? Can I perform a FEM analysis without geometry in Abaqus? Thank you for your help. Best Regards. RN
No dear,
If you are using slicer you will get .stl file only. No meanings of importing geometry then.
If try to generate surface from the stl file it becomes more complex.
So i suggest to use Hypermesh for meshing and use orphan mesh in Abaqus.
@@arsitech-ltd Thank you, Dear What are the disadvantages of not having a geometry performing FEA in Abaqus?
Lots of disadvantage dear,
Everytime for meshing you need to call model...you can't modify in Abaqus.
Loaf and BC you have to create on node sets or element set...you don't have geometry..so selection is difficult.
Defining contact is full of headache...
Etc.
@@arsitech-ltd Thank you for your answer dear. Why do you consider the element "C3D10" the best element for this anatomical application?
No.
Please go through the video - element family in Abaqus. Avilable on my channel.
Can you please tell how to assign material properties from CT scan to do analysis in abaqus
Not sure how to find material properties from CT scan.
hI SimTech05, can you make a video using this mandible in abaqus, applying some hypothetical muscle forces and some restrictions and made a fea analysis?
Dear,
Intension of video is to show the way to import such complex bone models in Abaqus.
I believe you can perform analysis without problem.
Sir I have little doubts in my project can you help me up ...I m a final year student ..very raw in abaqus.....I wanted to reach out in many ways ...but couldn't...but today I tried to connect you with linked in ...will you please help me out with the project ...???
Dear,
I'll try to help. Plz let me know where u stucked ?
@@arsitech-ltd I messaged you via linkedin sir
Hello sir, Where do you get your dicom data from
Dear,
many Dicom files available on internet. Or for any specific model you can contact to respective labs.
how to convert ct to solid in solidworks
Dear,
Unfortunately I'm not solidwork user.
@@arsitech-ltd thank you
I will try with my body 😁😁😁
Hahaha...sure dear !
Sir kindly have a lecture on abaqus subroutines and umat files
Dear,
I'm not expert in UMAT.
I wonder why this channel gets less view. May be has less reach to audience. Professionals or students of this domain have less interest in it.
Dear,
May be people not much aware about my channel and videos... share with others..it will be helpful for them as wel for me.
@@arsitech-ltd sure
