COMSOL Solid Mechanics, frequency domain PML problem

Please login with a confirmed email address before reporting spam

I am currently working on frequency domain model. I am getting error, defined value found in the equation residual vector. In forums people suggests it is due to poission ratio, incomplete BC and mesh issue. I checked all parameters and found that this problem is associated with Perfectly matched layer (PML). When i disable PML my simulation starts running, but when I apply PML above mentioned error is obtained. PML setting is Cartesian, Polynomial, with both scale and curvaure factor as 1. top and bottom of PML is surface free while on side is attached with strucutre model and other sied is fixed constrain. For my simulation, PML need to be apply, can anyone help me in solving this problem.

Thanks in advance
