Hi Bartosz,
thanks for your reply.
So my first line in my input file is:
*MPC, USER, MODE=NODE
And are the following lines my nodes
n1, n2, n3, n4
according to the definition in the subroutine, as in x,u,... ? What if the subroutine is used more often than for one node-set? Do I list the other...
Hi all,
I've written a Multi Point Coinstraint subroutine in Fortran according to the Abaqus User Subroutines Refernce Manual Chapter 1.1.13. I want to include this subroutine in my input file. The input file usage (found in Abaqus Analysis User's Manual Chapter Constraints 28.2.2) is:
*MPC...
Triangular elements can have either 1,3,4 or 7 Gaussian points. I picked 4 Gaussian points as the integration with 3 GP was not as correct as with 4 GP.
But I could just use three Gaussian points and use the shape functions for the extrapolation, as I still don't know how to do a linear...
Thanks for your reply.
I would like for the simple linear interpolation, but ..
I checked the references. For reference 3, the number of Gaussian points and nodal stresses must be equal (I think), which is not the case.
I know how to do a linear interpolation for cartesian coordinates but not...
Hi,
I am currently writing a FEA program. I cannot find any information on how to extrapolate stresses from Gaussian points to the corner nodes.
The mesh constists of six noded triangular elements. The stresses are calculated on four Gaussian points. The shape functions are in terms of natural...
