Hello everyone,

I am working on a project related to helping the everyday researcher do his/her programming easier and faster.

I have done a fair amount of research work at OSU and have gotten a feel for the way they program on a daily basis, but realize that it could be and probably is drastically different on different parts of the planet. As such, I am here to ask the following questions (really, any opinion helps, so feel free to respond with whatever you want):

1) What is/are your language(s) of preference? (e.g. MATLAB/Octave, Fortran, C, C++, Java, Python, etc.)
2) Do you use a certain programming style? (e.g. procedural, object-oriented, etc.)
3) What, if anything, is cumbersome with what you use now?

hi, someone know how run abaqus models using user subroutines, I can run one umat with one model, but i need to run two umats in an unique model in a simple step..Thanks for you help!!

Hello all !
I need to build/use a 2D pseudo-spectral (Chebyshev) parallel Helmholtz solver.

Hi,

Does anyone have a small strain FE viscoelasticity routine or code that I can use, prefreably in Fortran? Thanks.

  The difference to the common model used is the f,g terms. The 3D FEM formulation has been derived and a new fortran program is written. The derivative matrix is symmetric. But the calculation result does not converge. I have tried every means to get a converging result. But it doesn't work, the residual norm always increases.

Dear All

I got the following error msg in Compaq Visual Fortran.
forrtl: severe (170): Program Exception - stack overflow
How to solve this problem?

Backus died recently.  This New York Times article reminds us of why Fortran was such a great innovation.
