Hello, I don't know if you're still around. I was studying your code, and was really impressed.

However, I do code optimization for a living and I saw that not even one restrict pointer was used in the code base.

That means, the whole code base possibly suffers from performance degradation due to pointer aliasing : https://stackoverflow.com/questions/146159/

I say possibly, since I don't know if you've used some other method to optimize your code, such that it performs as good as an equivalent Fortran code.

Without restrict pointers, it is my understanding that C/C++ codes can't be as efficient as Fortran codes, specifically for operations over large arrays of data.

Hi, bernardparent,
When I make the configpx for plasma_combustion_mixing.wrp, I got an error as follow:
No rule to make target 'arc'. stop.

It seems that .active is null.
How can I fixed it?
Thanks a lot!

Dear sir,

I am unable to generate the grid files out of the box. Kindly help me on this.
Thank you.

Kind regards,
