Detailed explanation about how to solve higher order differential equation using MATLAB
Hi Sir , can u tell me How to obtain the 3DPLOT file . and how to import the .k file in Ansys LS Dyna , and thank u
Hi, you can drag n drop the .k file once la Dyna is open
Though the governing equation of motion is same,why in explicit we determine acceleration and in implicit we determine displacement?
Sitting in IITD(LHC) Watching ur lecture
Hello I have some quaries, can i get your mail id for discussion
Very good explanation. Thank you
Is it better to draw a geometry file in SolidWorks and then import it in LS-Dyna, or directly in Ls Dyna? The geometry would not be just round circle. it has to be a little bit more complicated. Thank you
Yes , u can do so
Can you share the files again?
share the curves.k file
share the curves.k file. its not accesible
Excellent..thank you
Glad u liked it
@Knowledge_Engineering I can't access the linked Google drive files for the tutorial. Are they still there? Do I need to go through another site or be directly invited to view them? Thank you.
Hi Jessica , sorry for the missing file, you can download that from the LSTC tutorial webpage, if still you are facing problem pls let me know, I will upload here. But please try once
@@Knowledge_Engineering hello I can't find it on the website is it possible to upload the curve file here again please
sir can u share some source where we can find the prewritten example code for implicit in matlab
Nice 👍
Thanks for this video
Informative videos 💞🦾👍nice video
Thanks
Awesome that , India's car are getting 5 star atleast in Global NCAP rating. I hope number of road traffic fatalities will reduce after this great initiative by tata motors. BR Proud Indian
Agree
Very helpful
Thanks, Pls subscribe
Wow🔥
This was a good video.. Thank you
Thanks 🙏
Nice, double standards
No, bcoz of Indian government taxes, price will be very high if car was same as African
@@shahidshd4433 I agree , I hope govt will give priority to safety
Informative video👍
That's tragic 😳
Tata's are always best 💕
Yes Definitely
With respect to CFD which of the sentence is correct? The implicit method of the first order is considered for the discretization of time derivatives in the fluid equations OR The implicit scheme is for spatial and not transient derivatives
So explicit is used in CFD while implicit is used in mathematical modelling, is this correct? Where would we use implicit method in real life?
See, they are just 2 ways of solving equations, both CFD and mathematical modelling can be done either way.
@@Knowledge_Engineering thank you. If CFD applies to both methods, then implicit is used when you're looking at a problem over time - to ensure mathematical stability. Explicit is used when you are not concerned with accuracy over time, but want a fast solution. Is this correct?
Hi , can u help me over making Car impact model
Sure, pls write to me on pushpender.panday@alumni.iitd.ac.in
Hi cn u help me to impact on gypsum board
Yes sure, pls write to me on pushpender.panday@alumni.iitd.ac.in
Thank you Sir. You made it very simple to understand!
Thanks, pls subscribe
Please share the file
Pls check the description link again
I want to simulate the above in 2D using the Axisymmetric model in LSDYNA, is it possible?
Yes it is
I am working on solid particle erosion modeling your video is similar to that could you share more information about your modeling I am very grateful for your valuable information.
Hi , you can use *MAT Erosion in addition to your parent material of part. There you can define erosion/deletion of element based on various parameters like, stress , strain , etc.
excellent video!
Thanks
Hi.. where can I download the model to practice.
Its available in description section
Bro, I need to know how to simulate plate for damage. I know only density, poisson ratio, elastic modulus, max stress and max strain value. I need to simulate for different velocity. Which mat properties for plate is suitable.
Hey, you can use *mat piecewise linear plasticity and thereafter can define strain based damage if plastic strain at failure is known . Also, if effective strain ( elastic+plastic) is known than you can use *mat erosion in combination with plasticity model
Hi, how can I do post processing after I download your airbag1.k ; I use LS Dyna R11 version, thanks so much
Hey, you need to run it, using solver which will give you d3plots . Thereafter u can load your d3plots
I cannot find the d3plots, can you explain more details. It would be great if I can contact you via email or skype. Thanks a lot
Thanks a lot 🙏🏼
nice
👌
great video .. thanks!
Nic ... Can provide ur contact mail or no.

Great work... Much needed for such video. Keep it up
👍 great
Very well described and so informative. 👍🏻
Excellent explanation. Nice work❤️
Informative, very good work for FEA community
Nice
way of your explanation this topic is very well. I m waiting for your next video.its very knowledgeable👌👌✍️✍️
Thanks a lot 😊
Good job... waiting for nxt video.
Coming soon
Awesome explaination 👍🏻
My concepts are clear now
Quality checks summary: 1) Aspect Ratio should not go beyond 5. 2) Warp angle should not be more than 45°. 3) Jacobian should not be less than 0.5 4) Tet collapse should be greater than 0.1
Thanks for summary
