[Getfem-users] Error occurred when using add_nonlinear_term

[Tetsuo Koyama]

Dear GetFEM++ project

I have a error when I make a C++ program (in attachment file) by using
getfem++ library.
I compile it in Ubuntu18.04 and compile it in the same environment
compiling in tests directory.
The message is following. I'm sorry that I couldn't understand what
does this mean.
I could only understand that it caused because of adding the following
brick  in line 293.
  getfem::add_nonlinear_term(model, mim,
"lambda*Grad_Dot_ux1*Test_Dot_uz1", LEFT, false);
Could you please teach me that what does this error message mean?

Thank you for reading.
