Applying Two proportional load in the same node

[Mohammed Naji]

Dear All,
I have a 1D model, and I need to estimate the distribution of chloride and also humidity (2 dof) along the sample.
So I have to apply 2 type of proportional loading (chloride concentration and humidity) on the left side of
model simultaneously, where the equation of chloride transport also depends on the humidity evolution.
I can't do the solution commands (especially: PART and PROP) although I have tried the attached Input file but
 it didn't work.
How can I correctly use the solution commands.
 Thanks a lot.

Which version of FEAP are you using?

In ver 8.4 you can introduce load groups (this is not available in earlier versions or FEAPpv).  Otherwise you have to set the PROP as you have.  Since all is done in one partition you should not need PART commands.

Dear Prof. Taylor:
Thank you for your quick reply.
I did some work according to your reply here and
to other posts. I have solved most of the problem.
