The exact steps would be solver and solution dependent. The question is to vague to provide a detailed answer.
Recent versions of NX Nastran have dedicated elements for Plane Stress (CPLSTS*) and Plane Strain (CPLSTN*) analysis:
The definition of these is supported in Simcenter Pre/Post. The appropriate 2D Solid option must be set on the FEM to specify the plane that these elements will be defined on
Thank you Jim,
It is about a 106 solution. A pipe with with internal pressure.
Although I have defined a radial pressure (pressure2.png), when I do an Edit display I get pressure.jpg, that do not look very radial at all!
When I run the solution, it crashes (see solution minitor.jpg).
I am using inertial relief (inertial relief.pg).
Why don't you use 3d / 2D element normal prssure ?
After application it will be ideally radial for pipe.
Sincerely I do not see the option for application of this radial/axial pressure.
Where did you find it ?
Radial and Axial loads are used in context of an axisymmetric analysis. In the axisymmetric case, all nodes must be in the positive half of the axisymmetric plane.
For Axisymmetric analysis in:
In the Pressure.jpg image attached above, elements are defined in the XZ plane. "Radial" is the +X direction.
OK. Understood Jim. I have already applied pressure "on 2D solid elements (Normal to edge) ZX" (by the way, what is the meaning of "on 2D solid elements ZX"?). Pressure looks fine now, but my analysis crashes with the singular matrix message!
