hi.. everyone I'm a new user of Phoenics software. The geometry of my model is small.I want to solve using multi-blocks grids. How to transform the geometry to the points of body fitted coordinate? The points of block I are:P1(0,0);P2(0.5,0);P3(1,0);P4(1.5,0);P5(1.5,1)a nd P6(0,1).The block I (grids)is to be 5x15x1. The points of block II are: P2(0.5,0);P3(1,0);P7(0.5,-0.5)and P8(1,-0.5). The block II is to be 15x5x1. The points of block III are: P9(0.25,-0.5);P7(0.5,-0.5);P8(1,-0.5);P10(1.25,-0.5);P11(1.25,-1) and P12((0.25,-1). The blocks III is to be 5x15x1. I have the problem to combine the three blocks using MPATCH statement. How to combine Block I to block II and block II to block III? Thank's for help..

Try reading C:\phoenics\d_polis\d_enc\MBGRIDS.HTM

and inspecting the multi-block library cases.

Also consider whether you can create your problem as one block using objects to block out regions where flow is non existant.

Thank you for your reply. How to transform from the original size( the blockage type object) to bfc multiblock.
