                Week 2 Challenge : Surface meshing on a Pressure valve

                Objective:

                Aim:- To produce 3 meshes with diff target lengths and compare them for the given model Procedure:- First we check the Model for topographical inconsistencies, by using the geometric check option. Now we have several of these so to remove these errors we use the new tool in the faces section. After this we assign PID to…

                  Week 3 Challenge : CFD meshing on Turbocharger

                  Objective:

                  The volume Mesh generation involves surface mesh and topological cleanup as a pre-requisite activity So first we start with the topological cleaning We identify the Overlapped surfaces and proceed to remove the unnecessary surface. After this we proceed to work on removing single cons, triple cons, etc. we first check…

                  Week 4 Challenge : CFD Meshing for BMW car

                  Objective:

                  Aim:-      The Aim of this challenge is to create a surface mesh for the given model and its wind tunnel. The other main focus is identifying different volumes for volume mesh and choosing the most pertinent one. Procedure:-  We explore the model looking for geometrical errors. Our basic idea is that the car must be a…

                    Aim:- To successfully create a surface and volume mesh for the given model along with a wind tunnel free of topological errors and quality concerns. Procedure:- We first visually inspect the model for topological errors like single cons, triple cons etc. Here we see a lot of red cons, so we select the whole model and apply…
