    Comparing 2D model with 3D

    Happy New Year to all.... I have a 2D problem in Matlab where I have found the deformation of the problem profile. Now I need to compare the same thing i.e. the same profile but in 3D using Nastran. What I have done is, I have taken 0.1 degree of the profile and carried out the simulation. The...

    NX Nastran Applying Rotation

    I am doing a simulation in which I need to apply rotation of 10000 rpm to a ring. I have taken a 1 deg part of ring and not the whole 360 deg. When I do the simulation, the result which I get is not correct as I think because its getting bending in Y direction instead of like getting expanded...

    Applying pressure on a 2D closed profile

    I am doing a simulation where I need to apply pressure on the edges of my 2D profile but when I select the edge, the whole profile is getting selected not the single edge . And also when the whole profile is selected, the pressure is being applied on the surface and not the edges. Please help...

    How to apply pressure field in Nastran

    I have a excel sheet in which there is radius and pressure acting on radius. I have divided the radius in small parts and each part has pressure acting on it. The pressure is like increasing from low to high. Its not uniform.So at every new node new pressure. I need to apply the pressure on my...
