Material Parameters of Individual Nodes

Hello! It's a great tool you built there! I'd like to use it for some kind of topology optimisation. Is there an "idiomatic" way to set the material parameters of individual nodes? Thank you very much! JonnyB

Stress and strain convergence with mesh size
by kshargh.ali＠gmail.com Sept. 29, 2021

Sept. 29, 2021

Dear all, I notice something in my simulations and I wanted to share it with you. I appreciate if I could have your thoughts on it: In one simulation, when I uniaxially strectch a plate and change the mesh size, I noticed that the nodal stresses and strains remain in the same range. However, once I added an elliptical hole in its center, it seems that as I decrease the mesh size, stress and strain especially at the sharp edges of the ellipse goes up and do not reach to a plateau. My understanding is that it shouldn't be real and in fact should reach to a steady state. Please let me know what you think. Best, Ali

High Order
by Thomas Sharifi Sept. 13, 2021

Sept. 13, 2021

Hello, I am using SfePy for a project in aerothermal coupling. Congratulations for the amazing job done on SfePy and thank you for making it open source. I have a question regarding high order. You have a parameter integral, integrals = { 'i' : 2, } That we can set to the order we want. If I am correct, it represents the order of the polynomial shape functions and is used for the interpolation of the unknown variable in an element. I can't find anything about the shape functions, nor in the code, nor in the documentation. Could you help me and point out where it is coded ? Also, how high could SfePy support to go in order ? I tried to put different values to this parameter but it didn't seem to affect my solution in temperature. I thank you in advance if you can help me. I would like to talk to my supervisor about this during the week so I would be really grateful if you could help me as soon as possible. Sincerely, Thomas Sharifi, Sorbonne University
