Hello I am very new to comsol. I am working on the fluid structure interaction on an elbow pipe. I have the image of the model posted here. I have the fluid as concrete flowing through the pipe. I want to analyse the stresses and the deformation generated on the pipe walls due to the fluid flow. I got stuck at the point on how to select the solid structure for solid mechanics module for fluid structure interaction because in the model it is showing as a single domain that I have selected as fluid domain. Can someone help me in solving this
Thanks and Regards Sai Teja
