Talk:Windtunnel online

I ran the simulations for two different pressures. In both cases, I couldn't see the object. In my version, the solid is included. @Dennis also ran the simulation, but he didn't have the solid, so he re-wrote init.c. The object appeared in his simulation.

I tried to run the exact same simulation as Dennis, but there was still no object, just like before. --Shaghie (talk) 11:25, 5 June 2024‎ (CEST)

He didn't switch on SOLID in "makefile_user_simulationdefs" or he used a belt version, which cannot handle solid? Hence, he swiftly coded his own solid implementation? --Lothar (talk) 18:43, 5 June 2024 (CEST)

I don't know how this happened, but you have corrupted makefiles: The line

include $(BELT_DIR)/makefiles/makefile_automatic_defaultsimulationdefs

must occur (if at all) before the line

include makefile_user_simulationdefs.

Otherwise, the SOLID = YES in your "makefile_user_simulationdefs" is overridden by NO and your executable is missing the solid code parts. (One evidence for that is the absence of the files data/obj.*.dbl. They contain the indicator function of the object.) The makefiles in Rolf's "Sims/2021 windtunnel/2D/cylinder/dx=2mm/FlowRegimes/P=*/" are all correct, they actually don't include the automatic_defaultsimulationdefs at all. --Lothar (talk) 07:37, 6 June 2024 (CEST)
