udf plasma model
 

Hi all

i want to apply Shyy and Jayaraman's plasma model actuator on leading edge i dont know how to identify that plasma region in the udf for the equation E=E0-K1x-k2Y. note that the plasma region is a triangular

Can someone please tell me how to set a specific point for the applied plasma model? Or atleast locate the exact position of the applied plasma model in the udf thanks

if you want to get help on UDF! You should specify exactly your problem.
As for me, I don't have time and don't really want to go through papers to find out what do you mean

make sketch, show the code you have, explain problems

thank you for reply
to calculate the electric field E need values X and Y for the formula
so the meshes nodes in traingale AOB are indexed by element

C_UDMI(c,t,E)=E0-k1*x-k2*y;

so my question is how to impose on the mesh variables the zone where there is plasma...and how to index that zoneAttachment 73176
