Dear Yihao-Shi:

I got some trouble in import material file when using mpm model.

Funtion MPM.add_body_from_file error

MPM.add_body_from_file()->self.generator.read_body_file()->generator.begin()->self.add_txt_body()
->fix_v = DictIO.GetEssential(self.FIX, fix_v_str) 

In src\mpm\generator\LoadFromFile.py line146 may fix as follow (the same as BodyGenerator):

fix_v = vec3u8([DictIO.GetEssential(self.FIX, is_fix) for is_fix in fix_v_str])

Trackback is as follows:

unhashable type: 'list'
  File "E:\EX_library\GeoTaichi-fork\GeoTaichi\src\utils\ObjectIO.py", line 39, in GetEssential
    if keyWord in dict:
  File "E:\EX_library\GeoTaichi-fork\GeoTaichi\src\mpm\generator\LoadFromFile.py", line 146, in add_txt_body
    fix_v = DictIO.GetEssential(self.FIX, fix_v_str)
  File "E:\EX_library\GeoTaichi-fork\GeoTaichi\src\mpm\generator\LoadFromFile.py", line 69, in begin
    self.add_txt_body(scene, self.myTemplate)
  File "E:\EX_library\GeoTaichi-fork\GeoTaichi\src\mpm\GenerateManager.py", line 69, in read_body_file
    generator.begin(scene)
  File "E:\EX_library\GeoTaichi-fork\GeoTaichi\src\mpm\mainMPM.py", line 146, in add_body_from_file
    self.generator.read_body_file(body, self.sims, self.scene)
  File "E:\EX_library\GeoTaichi-fork\GeoTaichi\DGb.py", line 75, in <module>
    mpm.add_body_from_file(body={"FileType":'TXT',
TypeError: unhashable type: 'list'

Thank you for your reply.

Thank you for your reply! There are other problems in funtion MPM.add_body_from_file. I tried to fix them by myself. The detail I made change is in my pull requests. I have test it and it can works.
