visualize_density and max_iteration issue #7

Closed nilparent closed 4 years ago

nilparent commented 4 years ago

I ran the wheel_ script with cg_iteration = 50, however the optimization kept going after 100 iterations so I stopped it manually. Do you have an idea on how to fix this? Moreover the [ti vd fem file.tcb ] command is not recognized : `Loading module topo_opt

Running task [visualize_density]... [E 07/31/20 10:27:16.521] [task.h:create@29] Implementation [task::visualize_density] not found! [E 07/31/20 10:27:16.521] Received signal 6 (Aborted)` I tried visualize_density instead of vd but it still didn't work. And just a little question : is .tcb file convertible in .obj (after making it human readable?) or the solver does it automatially when it stops by its own (because my fem_obj is empty after running the optimization)? Thank you very much for your help!

This is on ubuntu 18.04?

Can you share the installation process?

EDIT: Installed it on ubuntu 18.04 (after failing to resolve few issues on 20.04), works! ti run convert_fem_solve <>.tcb.zip --with-density writes a .txt file with density values corresponding to each block. I was able to parse the file and apply a marching cubes algorithm to get the resulting mesh.

thanks a lot!
