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. [xcb] Unknown request in queue while dequeuing [xcb] Most likely this is a multi-threaded client and XInitThreads has not been called [xcb] Aborting, sorry about that.

Hi all, I have been creating the connection between the bow and bulbous bow by using the fillet surface method. You can see in the figure. The blank space is where I created the connection. It looks okay when I play with the parameters such as tangent factor and fillet length as shown below. However, when I want to do the optimisation by playing with parameters around it can give me the unsmooth curve connection as shown below. Do you guys have any suggestion on the way to make the geometry more robust to be optimized well.
