Hi Dip, if there is symmetry in the model, utlilize that to stabilze the directions that can be restrained with symmetry. For a pure temperature change, the Soft Springs option in the Study Properties is a good solution for directions that you can't clearly restrain.
As always, I caution you or any other CW user to minimize use of Soft Springs as a way to avoid having to think about restraints. It should be a last resort.
As far as temperature input goes, that should be pretty straightforward if you read the Help on this Load. Let me know if it doesn't make sense.
Thank you for response.
But analysis doesn't make sense.
1. I have restrained the sides of the shaft restricting motion inaxial direction only while the other two direction in-plane remainunrestricted.
2. Used static study - inertial relief option and referencetemperature at zero strain = 25C.
3. Applied temperature to whole solid body at 160 C
The fringe showing the distribution of displacement seems ok.
BUT, once we switch to VECTOR distribution it doesn't makesense
ALSO, the displacement in X direction is different than Y directionwhich should be equal as they are in radial direction.
