A data problem in FEM.py #55

Closed Jiang-Cui closed 1 year ago

Jiang-Cui commented 1 year ago

Dear Prof. Gerstmayr,

I have successfully install Exudyn in VS2017 and Python 3.7 in both Windows 10 and 11 with your help.

When I debug NGsolveCraigBampton.py in VS2017, a problem occurs as shown

2881c398ef6bebd8e14698c4f512f3c

I use the old-version FEM.py to replace the latest FEM.py, this problem is solved. Dose the latest FEM.py not suitable to the netgenBrick.npy and netgenHinge.npy generated by ngsolve?

As stated in the error message, if loading an old .npy file, you should set forceVersion=0. Alternatively, you can save the .npy file in the new format. Future versions of .npy files include a version and thus will not have this problem.
