Time evolution of dynamic contact angle
 
Hello All, I would like to know if there is a possibility of getting the information of time evolution of dynamic contact angle in the interFoam solver. I see that the expression of the dynamic contact angle used in interFoam solver is (dynamicGammaContactAngleFvPatchSclarField.C) as: theta0_ + (thetaA_ - thetaR_)*tanh(uwall/uTheta_) I am using the following bc in the gamma file as: wall { type dynamicGammaContactAngle; theta0 30; uTheta 0.1; thetaA 135; thetaR 75; value uniform 0; } I would like to know what I need to do to get the time vs dynamic contact angle information. Will this require some modification in the existing solver, or it can be achieved by using sampleDict or is there some other possibility. Thanks for your kind help. Regards, aa saha.
