Issue with running beam example

[karthik-codex]

Hello, thank you for sharing the project! I was having trouble running the built in example cases. I am new to Taichi so the code is a bit difficult for me to follow yet. I get the following errors when I try to run the beam model. the code goes untill it says "now we begin to assemble the sparse matrix" and then terminates with this error

and I get a lot of these warning before the simulation terminates.

Thanks for reporting the issue.

It seems that the project's syntax is incompatible with newest version of Taichi.

I test by taichi v1.6.0 and everything seems fine,
then I get the same error message as yours when I upgrade taichi to newest version.

Will find a way to make it compatible with new taichi soon, thank you again for reporting the issue and help us improve this project.

Hello, Karthik.

Recently I fixed this issue, so that the code can adapt to newest v1.7 of taichi. Feel free to try the newest updated version of FEMcy.

Thanks again for reporting this issue!
