Hi,
I need to use as an input in the Solid Mecanic module the Pressure results from Laminar Flow calculations. Can anyone explain me how to do this?
thank you for yor answer.
Best regards,
Leonardo.

Hi
Depending on your physics, you need to identify the Fluid pressure variable name (probably just "p") then you must ensure its valid on the common fluid - structure boundary.
Then you add a boundary load to the solid, select the boundaryof the fluid - structure I/F (interface) and add a pressure value of "p"
if the fluid has been solved (fluid flow before Solid) then COMSOl might alredy propose the link tothe other physics pressure variable for you in the Boundary load node

Good luck

hi
i am doing my project in digital microfluidics for that i need to apply different amount of voltage between an array of electrodes and a continous electrode and i want to apply laminar flow for the droplet actuation. can anyone help me to do this?
with regards

I have a two-phase level-set laminar flow system with an adaptive mesh refinement, and it causes issues with my Solid Mechanics coupling. Do you know of any way to get the adaptive mesh refinement to only solve around the fluid structure interface?
