Hi, I am using FEAP ver83. I am able to compile it and successfully run an example problem (Ex8, Iplast_2d, finite deformation problem, file attached) on my 32 bit machine (Ubuntu 12.04). When I try to run the same problem on my 64 bit machine (OpenSuse 12.2) I get an error. The last two lines of the output file are:
Computing solution at time 1.0000E-01: Total proportional load 1.0000E-01
*ERROR* Residual norm is NaN or Inf
The corresponding lines when run on a 32 bit machine are:
Computing solution at time 1.0000E-01: Total proportional load 1.0000E-01
Residual norm = 1.1423660E+03 1.0000000E+00 t= 0.07 0.01
In this case the code continues and terminates with no error.
I have made the necessary changes to the makefile.in before compiling FEAP on the 64 bit machine
and I could successfully run some other example problems (Ex1 (patch test)and Ex 7 (contact problem)) on my 64 bit machine.
Could you please help me fix the problem.
Thanks.
