*I am trying to reproduce results from a research paper. But my results are strangely opposite. I am trying to simulate residual stress after welding. First, I found the temperature distribution in transient thermal, which is ok. After that, I used the temperature distribution as a load in transient structural. And here, the problem starts. It is expected to get tensile stress in the weld line's vicinity and compressive away from it. But my results are exactly the opposite. Here is the temperature distribution(I am using a dual heat source of Goldak type)https://us.v-cdn.net/6032193/uploads/A4S6KG5CPBHK/image.pngConstraints to restrain the rigid body motionAt vertex C, all three displacements(x, y, z) are zero.At vertex B, two displacements(x, z) are zeroAt vertex A, one displacement(z) is zerohttps://us.v-cdn.net/6032193/uploads/O5NV8P6G76XR/image.pngThis is the normal stress in the longitudinal direction(Y). I gotwelding time = 20sec and cooling time = 130 sec. Total 150sec simulation. https://us.v-cdn.net/6032193/uploads/B3OJIH40A27Q/image.pngAnd below is the expected pattern of residual stress.https://us.v-cdn.net/6032193/uploads/OA7MBBAH9CK1/image.pngMy question:where am I possibly going wrong because my results are exactly the opposite of what is expected?*https://forum.ansys.com/discussion/25034/residual-stress-distribution-post-welding
