Default dynamic mesh adaption
Posts: n/a
I have some problems in using this function since I obtain a segmetation fault using the command adapt adapt-to-gradients turb-intensity space-gradient 1 n 0.9 0.3 y 10 y so I have to use adapt adapt-to-gradients turb-intensity space-gradient 1 n 0.9 0.3 y 10 n it works but if I add other variables with the same command and at set the same gap of iterations fluent displays only that he is refining in respect of one variable.. it is only an output problem or something wrong is happening inside?

Another question: which are the suggested values? I heard abt gradient of 1e-6 but is a normalized value I hope.. bcos I have scaled gradients of ca.60 and I do a refinement every 10 steps and the iteration converges..

Last: which are important adaption function? I have a flux around a bluff body and I set the gradient of the pressure and I dont know what else it's worth..

Thank you I'm a newbie...
