I am working in ANSYS multiphysics for vibration analysis of electronic equipments. To find out absolute displacement on cards in Harmonic Analysis by using Large Mass Method, I need to give 1g acceleration on Large Mass. I am applying (Large Mass*9.81*1) force on Large Mass so as to simulate 1g accleration but response at same LM location after analysis is coming 2.5g. Can anybody suggest any alternate method of doing it?
