Dear OGS community,

I’m modeling the liquid flow and heat transport through a 1x1 porous media enclosure

and I face a problem regarding to the velocity components on the nodes in z direction.

I’m studying a 2D problem in x-z direction. The problem is now, after the computation I get velocity components in y direction instead of z direction in the tecplot files. As a second dat type I chose PVD, hence I get there VTU files in a right order with y velocity components equals to zero.

After a comparison of those two velocity components in z and y direction, I recognized that they are matching.

My question is now, why isn’t it represented as z velocity components and is it really the z velocity component or did I make a great mistake during the set up?

In further simulations I only defined

VELOCITY_X1

VELOCITY_Z1

as node values, therefore I was quite surprised to see the latter components equals to zero.

Can anyone explain me this phenomena?

I have another question concerning the liquid flow tecplot file. There it is showing

VARIABLES = “X”,“Y”,“Z”, “PRESSURE1”, “TEMPERATURE1”, “VELOCITY_X1”, “VELOCITY_Y1”, “VELOCITY_Z1”. I wonder why the temperature values aren’t in the range between 273.15 and 274.15 because these are the boundary conditions on both walls.

Can anyone explain me this as well?

You’ll find the model attached.

Thanks a lot and

best regards

Tuong Vi
