      Hello All,nI am planning to perform a Transient Analysis on CMUT (Capacitive Micromachined Ultrasonic Transducer) Membrane.nFor that, I have two case ncase 1: na 20-ns-long 70-V pulse is applied to the without dc biasnnCase 2:nthe device is driven by a 50-V, 5-MHz, 1-cycle tone burst with no dc bias.nnI have to use Trans126 element so I have to EMTGEN command but I don't know How to interpret this two different case and How can I apply?nI am using Ansys workbench but for this loading, I am using Command snippet (APDL)nnCould anyone please help me to apply this loading condition?nI have a fluid medium on top of that so my aim is to find out Pressure after applying this loading conditioThanks and Regards,nDhruvi

      Never used this element but from the example in the apdl manualnnYou can use the D,NODENR,VOLT,%VOLTTABLE%nTo assign a volt table called %VOLTTABLE%nnSee this example in the apdl coupled physics chapter 2 for more info on this element:n2.9.8. Example: Electromechanical AnalysisnnThis is a good resource also for time tables - also the help manual has relevant info:nnThank you and I hope this helps because as I said I have not used this elementnnErikn
