Temperature definition using fields in Three directions

prasad.guduguntla.external over 4 years ago

Hello,

I need to define the temperature for 3D Cylindrical structure. The nodes are defined in Cylindrical Coordinate System and the temperature varies in ( R, Theta, Z ) in all three directions at interval of 25°.

The thickness of structures varies in Radial direction, because of that the R is not constant and it varies along the height.

I tried to create the fields by changing R at each height using PATRAN, I am not able to define it .

It's not a equation or experimental data, the nodal temperature at certain points are extracted from the thermal analysis. These points are defined in Cylindrical CS.

Now I need to consider these points in a Nastran model and interpolate between the points.

The temperature points are not directly at nodes of the FE Model.

Yes at an interval of 22.5°

Thanks
