Two volumes in one rotating region

To analyse the flow in centrifugal pump it is important to analyse the flow in only one shovel canal. For improving the flow characteristic, and see the flow around the shovel egde.   It could be made if it is possible to have two volumes in one rotating region (see attachment).   Or make it possible to overlay a rotating movement in an flow area, like it is possible in other CFD solutions.   Now it is very hard to get a look to the flow in the impeller.   Please aktivate the groups (volumes and surfaces) of the configuration mode in the result mode   It is important to see the pressure distribution on shovel surfaces, now it is always very hard Show More

HPC cluster integration

I wish for a seamless cluster integration. I have seen some chronic problems in integration with cluster in 2013 and it seriously affected the timelines.    Also, there should be a provision to run two jobs in parallel (say 8 cores each) so that we can complete the simulations earlier than running them on series with 16 cores.    Regards OJ Show More

Orbit center

Everytime I copy a scenario, I have to setup the orbit center to the convinient location. Now, since the geometry for all the scenarios in a design study is same, the perfered orbit center would be the same as well! It would be nice to set it for first scenario and then forget about it.    OJ Show More

CTM Visualisation

CTM's have a gap around them when viewed in the results - is there a way to remove this so that it looks like everything is connected? (Even though it is not, I know).   Request from Maxime Bomme of Aplisim Show More

Cut plane save table

Hi, it will be really helpful if you can implement in script the save as table from a cut plane. This will allow us to compute custom informations from the results of that plane. Say for example I need the medium temperature defined as:   Tmean =Integral (u T ) da/Integral (u) where u is the velocitiy in the flow direction   saving cutplane as a table from script will allow us to automate the extraction of data and then unsing an other software such as Mathematica to compute that quantity for more that one scenario.

Reduce the minimum mesh spacing

On large domains exporting data is only possible with a mesh that is too course to accurately represent the flow in the around detailed geometry. This can be solved by allowing for a finer mesh spacing in the area of interest or indeed in the entire domain. Show More

Treatment of conical strainers

We deal with conical filters made of perforated sheet a lot and currently, the only way to model them is to use surface resistances. Now, often this can be a significant simplification since:   the velocities are averaged before the strainer to be applied in the Darcy's equation (instead of choosing only normal components) all the streamlines are made perpendicular to the strainer surface as the fluid leaves it, which can be unphysical since there is no expense of pressure/energy in doing so I would like to use a porous volume of conical strainer, with finite constant flow through coefficient in "Flow direction" and very large (1e8) coefficient in "Flow directions (1 and 2)". And I want to specify the conical surface of the cone to specify the cone direction, which is not exactly radial!   I tried using radial option in this but surprisingly, the fluid doesn't "see" the strainer nad behaves like it's fluid region!   Hope I see some improvement here.    Regards OJ Show More

Expand geometry options for TECs

I recently heard of a need for modeling non-cuboid Thermoelectric Coolers (TECs) in Simulation CFD. Currently TEC material devices require a 6 sided cuboid part. Requests have come in for modeling round TECs with center holes similar to these units:   http://www.tetech.com/Peltier-Thermoelectric-Cooler-Modules/Round-Center-Hole.html   Does any one share a need for modeling this kind of TEC? Curious to know how often they come up.   Thanks, Jon Show More
