keep getting errors from blockMesh saying: "negative volume"
Hi everyone,
I am very new to OpenFOAM and after much pain and struggle, I finally installed OF 2.3.0 on VMware player with Ubuntu 14.04 32bit. Eventually, I want to implement an actuator disc model and do some flow analysis. I tried googling and got some info but it is just overwhelming for me - going no where. This is a noob question - but is there any CAD software that can automatically generate this blockMeshDict file? So, right now, I am learning how to use blockMesh and create some simple mesh according to this tutorial I found online : http://www.fm.energy.lth.se/fileadmi...rExercise1.pdf My blockMeshDict code Code:
/*--------------------------------*- C++ -*----------------------------------*\ Any help is really very much appreciated! Thank you! |
Greetings hwsv07 and welcome to the forum!

If you visit that thread, it will point you to a wiki page, in which you'll find a section entitled "Graphical User Interfaces for visualizing and designing blockMeshDict": http://openfoamwiki.net/index.php/Bl..._blockMeshDict :) Quote:

Hi wyldckat,
I took your advice and broke up my mesh into separate blocks and found out my problem. I mis-read how I should number my vertices. so now I have to managed to generate my 3 blocks. However, I still have a problem. I have specified a curve edge, but when I previewed my mesh in paraview, it does not show me the curve edge. Is there something I did wrong? How I did to preview mesh was as follows: Code:
blockMesh -blockTopology I then opened paraview. blockCentres.obj does not show me anything, but blockTopology.obj only shows me the outline, but I cannot see the mesh though (I selected Wireframe under Properties - I tried some tutorials, and I know using WireFrame allows me to see the mesh grids). Am I doing something wrong here? I also tried to preview mesh by just running Code:
blockMesh Code:
user@ubuntu:~/Desktop/Link to MySimulation/pipe$ paraFoam Below is my blockMeshDict. Code:
