About post processing skills
I have a simple question.
To obtain the load-displacement data or graph from femgv, how can I get the total
reaction at support by summing the each force at each node on the support?
Is it possible to sum each reaction force on node located at support surface or line?
I could not find any tutorials or examples.
Please help.

I'm using the Fx+ for Diana as pre-postprocessor for my analysis. Normally to obtain the load-displacement curve I re-edit the results in excell. Is it possible to obtain it directily in the Fx+?
Thanks
Here is an example generated in the manner htca described: http://www.tnodiana.com/upload/files/DIANA/HTML/Examples/node240.html
It's part of the Squeezed Disc example: http://www.tnodiana.com/upload/files/DIANA/HTML/Examples/node227.html
I think the easiest solution to compute the sum of the reaction forces is to use the command RESULTS CALCULATE INTEGRATE LINE(see section 21.2.7 of the Pre and Post Processing manual : http://www.tnodiana.com/upload/files/DIANA/HTML/Diana.html ).
I hope it will help.
Hi Jean-Claude,
Integrating nodal results may lead to a wrong answer. Only when the supports have intermediate distances of the unit of length, the integral will give the right result. I'd prefer using tyings and ask the boundary force of the master node.

It is better to use tyings to find the resulting force.
If you 10 points, make 1 master and 9 slaves. support the master and find the resulting force in the master node.
