Tutorials

Here you can find a video tutorial how to install the software and video tutorials how to perform filling simulations for RTM parts. Also one video tutorial shows how to perform filling simulations for a VARI part.

Introduction into RTM

This video tutorial gives an overview of relevant topics for RTM filling simulations.

LCMsim v3 installation

This video tutorial shows how the LCMsim software is installed.

Here you can find the links to the GitHub repositories: LCMsim v3 on GitHub, GUI for LCMsim v3 on Github,

Radial RTM flow

The following two video tutorials shows how background and simulation of RTM flow inside a radial flow permeameter.

RTM validation case

This video tutorial shows how to reproduce the results from validation case 1 from the validation paper.

RTM filling with meshing

The software PrePoMax which is used for mesh generation is available on the PrePoMax download site

This video tutorial shows how to create a mesh and afterwards run a simulation with this mesh. Several applications are studied: Permeameter experiment with own mesh and annulus filler. For the annulus filler rear injection gives converging flow fronts, front injection does not. For front injection the location of the vent can be determined as the region where the flow front arrives at latest. For the annulus filler also cascade injection is demonstrated, although this is used for larger parts as for the winglet spar.

Grphical point selection for reference direction and inlet positions is possible with key "p" + left mouse button clicked.

VARI filling simulations

This video tutorial shows how to perform filling simulations for VARI parts.
