Gambit2.0.8 (for Mixsim): revolving a face to create a volume creates a so-called degenerate-edge vertex... |
I create a face from a (more or less arbitrary) edge loop. I then rotate the face around a straight edge that is part of the face. The volume is generated, all edges of the face disappear, but a... |
Calculate radial, tangential and axial velocity components in UDFs |
A user wants to apply an energy source term that is function of radial velocity. Since only velocities in cartesian coordinates are available through UDF, this routine was created to calculate... |
In the energy equation, when Viscous heating is turned on, Pressure work must also be turned on. |

Users want to know directly what is the NAME of a zone with a given ID |
This is a question heard from many users who wanted to find out quickly what is the NAME of a zone, given the ID<br>of that zone. The reasons for having the ID of a zone, but not the name of... |
Being able to specify automatically a naming convention based on type+ID for all the zones in a case file |
In a case file with a large number of zones, the task of enforcing a certain naming<br>convention based on each zone type and ID, would be daunting if done manually.<br>Hence, provide... |
How to get number of particles escaped through a zone? |
Lets say we have uniformly distributed rain particles released from inlet. Lets say we have two outlets (outlet-1 and outlet-2). Air carries the particles and some escapes through outlet-1, some... |
How to specify velocity-inlet to interior faces types. |
There are cases where user wants to specify velocity-inlet to internal zones. For example, lets say we have a cylinder completely inside the a box. Lets assume that inside of the cylinder is... |
How to use local installation of Real Gas libraries |
