Hi,

I need to calculate the wallShearStress using the multiphaseEulerFoam solver (OpenFOAM 9).

I used the funkySetFieldsDict function as follows:

        wallShearStress
	{
		field               wallShearStress;
		create              true;
		aliases             { Uwater U.water; }
		expression          "sqr(sqrt(3e-7*mag(snGrad(Uwater))))*7800";
		dimensions          [0 2 -2 0 0 0 0];
	}

I squared u_Tau and multiplied it by the density of the fluid.

However, the snGrad() function has apparently been suppressed. It made an error. Can anyone help me calculate the wallShearStress?

Hello,
I am not sure how to do it with swak4Foam. There could be other people who can help you with that.

However this functionality has been implemented in OpenFOAM v11.

You can see the code and possibly try to implement it in v9.

Good luck!

Hi,

I remember you helped me and I would like to ask for your help again... I created the topic below, if you can visit it.

wallShearStress - MultiphaseEuler - turbulence model

Thanks.

Hi,


I managed to compile, but without much success. If you can help.
