Hello again, Now, I am trying to run my code faster and therefore am trying to avoid writing in files as much as possible. With that said, I want to create an array, that is not going to be reinitialized in every time step but only updated. Is there any nice solution to this or should I use cs_field...

Hello Yvan,

thanks for all the help, with your recommendations my code is running well now.

Kind regards,

Hi there, I am sending the file through attachment. I have also tried with my own function to find the global minimum, but was not successful. I think the problem is not in the function itself, but with the parallelization. I must have done something wrong there. But as I see it, I find the local mi...

Hello, thanks for the example. I have occurred another problem. I am calling function findpt (predefined) and am getting following error; extra_operations.o: In function `cs_user_extra_operations': extra_operations.c:(.text+0x240): undefined reference to `findpt' collect2: error: ld returned 1 exit ...

Hello, I am simulating flow through an annulus. I want to extract a profile at different r=R and calculate an average. I would basically average my field over phi and z. I saw that there is a 1D profile extraction possible (cs_extra_operations-extract_1d_profiles), but what would be the best way to ...

Hello, I am simulating some unsteady flow through annulus. Because I am not sure of the velocity profile at the inlet (I just know desirable Reynolds numbers) and I want to create turbulent flow, I am planing to do the following procedure. Firstly, I define some random velocity profile and then afte...

HI again, I tried outputting only one velocity field at once and it does not work that either. If I try to output scalar and velocity fields it outputs scalar but does not output velocity. I do not have any other ideas currently, so any suggestions are welcome. Kind regards EDIT: Spotted the problem...

Hello, I tried to put only velocity x without a scalar, but then it does not output anything. I also tried to put everything on one writer and it does not work that way either, but didnt play with it as much. I`ll try with everything on one writer. The domain is the same for all three fields. Thanks...

Hi, I am using Code Saturne with Melissa software. I try to get it to output three different quantities. Scalar(concentration), velocity_x and velocity_y. I do it with cs_user_postprocess_var.f90, but I only manage to output the scalar field, the other two are empty and I am not sure what is wrong w...

Thanks to all replies. Sorry I didnt answer earlier, but I got to make it work. It was a problem on my side.
