Objective- Geometric cleanup and CFD meshing of the TESLA cybertruck.   Introduction- Below is the image of the Tesla cybertruck on which we have to perform geometric cleanup and CFD mesh-   Procedure- As you can see in the above image, there are lot of single cons. So we will have to use topo tool on the cybertruck.…

Objective- To surface wrap on an automotive assembly which consists of engine, gearbox and transmission after geometric cleanup and merging of the individual parts.    Introduction- The surface wrap tool wraps the geometry of interest to create a volume that does NOT have intersecting surfaces or non-manifold…

Objective- Geometric cleanup and CFD meshing of a BMW car.   Introduction- Below is the image of the BMW car model-   Procedure- Initially we have to rectify all the geometrical errors in the model before surface meshing. As you can see the image above, there are multiple errors in the model and we will remove the errors…

Objective- To mesh the surface of a pressure valve.   Introduction- A relief valve or pressure relief valve (PRV) is a type of safety valve used to control or limit the pressure in a system; pressure might otherwise build up and create a process upset, instrument or equipment failure, or fire.…

Objective - Surface and volume meshing on a turbocharger.   Introduction- In an internal combustion engine, a turbocharger (often called a turbo) is a forced induction device that is powered by the flow of exhaust gasses. It uses this energy to compress the intake gas, forcing more air into the engine…

AIM- To write a program to parse the NASA thermodynamic data that can be used to calculate thermodynamic properties of various gas species.   Parsing- Parsing a file refers to reading a data file and building a memory model of the content of that data. This helps us to perfom some kind of transformation on the data.…
