no in OpenLB download


I am very new to this

I downloaded the OpenLB and unpacked it onto my linux computer. I ran “make” in one of the directories for an example and that worked fine. When I try to run it though I get error that I don’t have the on my computer.

The user manual says to make a makefile, go based on the in the root directory but I don’t have that. I’ve searched my computer for it as well.

Any suggestions?
