Hi
I am trying to measure the resistance of a conductor with irregular geometry in Abaqus
I can currently do this by using
-A standard & explicit model type
-A coupled thermal electric step
-Apply a 0V boundary condition to one end of the conductor and a source voltage to the other
- I can then measure the current density field magnitude ECD in an area with constant cross section. multiply that value by the cross section, then use the found current flow to calculate the effective resistance.
This is not ideal however and I would like to simply measure the current flow from one of the boundary conditions as a history output.
I found that you can add an integrated output section and use the SOE output variable.
(This may only work for a Coupled thermal-electric step)
First define the surface you want to measure current flow through in the assembly or part
Then create the integrated output section (step module, Output->Integrated output sections->create)
Then add a history output request. Domain=Integrated output section, select the section you just created.
Then you can select SOE, Total current across the surface. (Under Electrical/Magnetic
This will then allow you to plot a graph of current flow through that surface.
I think, in Abaqus/Standard it may look like this: create MPC at one end of the conductor (type – equation, DOF= 9), apply electric potential BC at its reference point, request history output variable RECUR (reactive electrical nodal current) at this RP.
