Hi all, I am having difficulty in simulating a capacitive sensor modelled in Ansys 7.0. My main concern is measuring the capacitance change for a change in deflection of two plates. Can anyone help me understand the process that should be followed to extract the capacitance after the deformation has occured due to some structural force acting on one plate. I can calculate the capacitance using the CMATRIX macro for a static model but I need suggestion for the coupled analysis of the model. first structural and thene electrostatic. I would appreciate if anyone can help me out. Thanking you --------------------------------- Do you Yahoo!? Free Pop-Up Blocker - Get it now
