HI,

How can I see mesh stiffness through my domain in cfd post?

I have written an expression for mesh stiffness and I want to know How it affected on my domain.

Thanks.

Create an additional variable and set it to algebraic expression. Then set the expression to be the CEL variable you defined as your stiffness. Then it will be put in the results file same as the other solution variables.

Thanks ghorrocks,

I can create a variable and set it to an expression but I don't know how the expression should be written?
I don't have wall distance to use for my expression in cfd post.

and what is mesh diffusivity?

thanks

I used Increase Near Boundaries for mesh stiffness,model exponent 4 and reference distance Global Length Scale.
what is its equivalent expression?

Thanks

Don't you have any other suggestion? I need to do this to find out ho much mesh stiffness has been effective.
thanks.

I can't help you with your latest question.

Thanks ghorrocks,

Do you think it is even possible to see the stiffness of elements through domain?
I checked cfd post but I couldn't find anything like wall distance or anything even close to it to write an expression for stiffness in cfd post. It seems cfd post also doesn't have any variable or expression to do it.

thanks anyway
