Polyurethane (PUR) foaming simulation of a car dashboard can perfectly be performed with our CFD software NOGRID points. The software can help to understand the flow inside the cavity. It can show the entrapment of air, the foam density distribution of the isolation material and the pressure of the PUR foam acting on the cavity.

NOGRID unites abilities to handle free surface flow and moving parts in the domain and allows the simulation of any conceivable geometry and operation modes such as

computation is in full 3D solving complete Navier-Stokes-Equations
easy and intuitive setup of the PUR foaming case
free definable PUR material properties by equations or curves
polyurethane (PUR) injection by one or more inlets
open or closed domains including moving of additional parts
moving of the mixing head

Nogrid's strengths

Particular strengths of NOGRID's fluid flow CFD software are the rapid preprocessing (no fluid grid needs to be generated, only the boundary mesh, inner finite points are generated automatically depending on User setting initially and during computation), and the outstandingly short computation time even for complicated cavities.

As you can see in the image below, the boundary of the geometry still requires a mesh to allow the interior finite points to detect the boundary. The boundary must therefore be meshed and the finite points inside are automatically generated during the simulation controlled by User specifications.

Easy and fast modelling: Build geometry, mesh boundary, setup the case and start computation

What is CFD from NOGRID?

CFD solves the fundamental equations that define the fluid flow process. With CFD software from NOGRID every engineer makes better decisions by predicting, analyzing and controlling fluid flow, heat and mass transfer or chemical reaction. By using NOGRID software for flow modeling you receive information on essential flow characteristics as for example flow distribution. Using it additional to testing and experimentation NOGRID software helps to improve the evaluation of your design – resulting in better construction and operation parameters, increasing planning security and money savings due to faster time to the marketplace for your product or process.
