Nuttarat.Vichanphruek 0 Report post Posted March 16, 2023 Hi, Recently, I connected CAESES to a CFD software. I manage to run a Design Engine by this connection. However, 50% of the time I will get error as shown below while it worked without problem as well 50%. I am not sure that it randomly occur or what is the reason behind this. If anyone could help and have some idea thanks.
