incompatible dimension for operation means??
 

Hello,

I made a new solver and ran it successfully without any error.


Afterwards, when I tried to run my case I got an error. What could be the reason behind this error???
Do I need to re-check my solver? Is it the error of solver?


Error is shown below:

Calculating face flux


Starting time loop
Time = 0.0005

Courant Number mean: 0 max: 0.0349808
diagonal: Solving for rho, Initial residual = 0, Final residual = 0, No Iterations 0

openFOAM check the dimension of operator before execute it so look the dimension of ur equation!

What do you mean by this? Do you mean that you compiled it without any errors, or did you actually run a case with it?

Looks to me that one of the terms should be multiplied or divided by density rho (the dimensions are off by kg/m^3). Either there is an error in the equation your solver is solving, in which case you should correct the equation and recompile your solver. The other possibility is that a field in your case has the wrong dimensions; the field in question being most probably the field phi. If you have a file called phi (it could come from you copying a 0/-directory of an existing case) in your <case>/0/ -directory, try deleting it and then rerunning the case. The dimensions of phi are different for incompressible and compressible cases.

Hello Joel,
 

"
Hello,

I made a new solver and ran it successfully without any error. "

By the above line. I mean to say I did a successful compilation of the new solver that I wrote.

In the second part of the question

It looks to me the first mentioned suggestion is right. I wrote an equation in the solver from there this error continued. Anyways thanks a lot..

Hello nimasam,
 

The problem actually came from the "dimension of operator" as you have mentioned. I rechecked my solver.

Thanks a lot....
