Hello,

I have created a 3D geometry on GMSH (v. 4.5.6) software that resembles a T-junction with fluid flowing from both the side and the center inlet to the outlet at the end of the channel. I created the geometry using points and lines, as well as defining plane surfaces and one volume. I have my geometry file attached (Tjunctiongeo.txt).

When I construct a 3D mesh and upload it to MATLAB using the importMeshGMSH routine provided by QuickerSim (routine code attached below), I get the following error:
"Unable to perform assignment because the size of the left side is 3-by-74930 and the size of the right side is 3-by-73290."
Error in importMeshGmsh (line 308)
e(1:3, = tmp(tmp(:,2)==2,6:8)';

The 'e' matrix defines all of the mesh boundaries. I have tried to redefine the mesh at specific points, ensure that the mesh file version is compatible with the matlab software (2.2), but I still cannot seem to find where the problem is with the mesh generation. I have the option file attached with information on the mesh and the geometry. I'd appreciate it if someone can guide me on where the problem may be? I think it could be with how I also define my surfaces, but I am unsure. Thank you.

I apologize I forgot to post the code of the routine, here it is attached
