Hi,

 

I am getting the following error:

  *** INTERNAL PROGRAMMING ERROR ***    in file 'trmtxl2b.F', at location # 63.           ioerr(1) = 2146697216  ****  ABORTING RUN DUE TO AN INTERNAL ERROR  ****

The model has Tie contacts and Mat9Ort as material for the optimisation property. I didn't have any problems with Mat1 as optimisation property, but as soon as I am trying to useorthotropic material I am getting this error. I already checked the material parameters according to the documentation of Mat9ort and all seems fine.
