Resistor definition in Piezoelectric bimorph with ANSYS workbench

Hello, good day! I am trying to simulate similar bimorph piezoelectric harvester with below commands. However, the output power doesn't change with resistor value. Please help to find the reason. ET,10,CIRCU94,0 !SET UP RESISTOR R,1,100000 !RESISTANCE VALUE TYPE,10 !SET ELEMENT TYPE E,1,2 !CREATE RESISTOR BETWEEN NODES 1 AND 2 Thanks in advance Regards,

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...

Why almost every element would be metallized in sufficiently high pressure and low temperature?

(This statement is from wikipedia, BTW). What is so special about metallic bond that is limiting high-P low-T state of a matter (as long as individual atoms exist, not white dwarf of neutron star...

LOAD DISPLACEMENT CURVES Stiffness increasing in ANSYS non linear analysis. HOW CAN I CORRECT IT?

Hi. I am doing non linear FE analysis using a new material beam under flexural 2 point loading using ANSYS. I have defined a bilinear material model. The solution has converged. In results I am...

What does dS, dS[eqn] mean ??

Ram Kumar Pal

Dear friends, sorry for replying too late, I was busy in PhD entrance test. In udf the term DS[eqn] is used to linearization of source term which ultimately help and improve in the convergence of solution. To know more about this term see "Source term linearization" in any CFD book.

Dear Haghani, the udf that is attached here in this thread is not correct. I have made some correction in this udf. Currently I'm busy in my project work. I'll contact to you for details via email that is written above by you.

thanks

Mr Ram Kumar Pal,

I am doing my final year project on heat pipes . I need to make simulation of a heat pipe . I am not able to simulate the condensor region properly , I refered many research articles in this respect , it was mentioned I need to use a udf code for it. Can u kindly share ur corrected udf code . It would be of great help . Thanks in advance
