  1. Hi, How compute the correct behaviour of an anisotropic magnet in 3D during the solve? Grazie!
  2. Dear All, I want to make electrical simulation combine with thermal (heat transfer) aspect on complex assembly. I've made the FE model with hypermesh optistruct profile and export as .fem file, but I can not import it to FLUX. Is there any way to do it? Please, need your advise. Thank you, Best regards, Iron_Man
  3. Hello, I can't solve the problem with model prepared in HyperMesh and exported to Flux. Model consists of two cylindrical coils on yoke, a solid conductor below them and the surrounding tetrameshed air. Analysis is set to magnetostatic. There is no non-linearity in any material Chesk physics doesn't give any error. Whenever I start to solve problem, Flux gives: "End of physical check. 12:03:00 9 sec.

  4. Hi, I'm trying to import a file from FLUX software, I export the geometry from FLUX in .IGES and .STEP. In both extension the imported geometry in hypermesh is uncomplete, some solids there are, other no. some lines are ok, other are free lines with no connection. I found a lot of problem in rebuilt the geometry with no succes. How can i fix this problem? is there someone how can works with both programs with no problems? Grazie!
  5. Hi! When you import a FLUX object in your project, if there are common parameters, with the same name, the software automatically changes the name of one, adding suffix "001". For example: I have the parameter <H = 5> in my "toimport.FLU" project, and the same <H = 5> in my "main.FLU" project. When I import "toimport.FLU" in "main.FLU" he automatically create the parameters <H = 5> and <H001 = 5>. There is a way to not let FLUX doing this? i'd like to have only one parameter <H=5> for all the project. Grazie!
  6. When closing sketcher context i receive the following error. Am i doing something wrong? Method "glGenBuffersARB" not available
  7. Could someone help me understand the following error? Im new to flux and this is the first simulation i tried to make. INFINITE: This region is not completely characterized In Physical, [MODIFY] [REG_SURF] [ELECTROSTAT_AXI] Impossible to solve problem
  8. Going to materials in the physics tab i only see the option new b(h) curve. I want to add a new material but the option isn't there. Did i do something wrong in the simulation or maybe have a setting wrong?
  9. In order to compute accurately the force on a part using the virtual works method, the part must be surrounded by air. There can be massive regions or thin regions of vacuum type. Theoretical explanations about virtual work method can be found in the online help: file:///C:/Altair/Flux_12.2/Help/Flux/english/Website/InterpretationDesResultats3DEnergieForceCouple.html?key=results energie torque force
  10. This question is frequently asked because three current sources in star connection can lead to convergence problems (and as well three voltage sources in delta connection). This configuration imposes more equations than there are unknowns to find during the solving process. The easiest solution to avoid this issue is to model only two sources instead of three. The voltage or current on the third branch will be imposed by the two others, and the computation will be correct. Flux online help explains it with more details: file:///C:/Altair/Flux_12.2/Help/Flux/english/Website/index.html?SourceDeTensionTriphaseeEnTriangle file:///C:/Altair/Flux_12.2/Help/Flux/english/Website/SourceDeCourantTriphaseEnEtoile.html?key=current sources It is also correct to model the three current sources, but a high resistance must be added in parallel with the 3rd part of the star connection.
  11. The macros enable the user to regroup the frequently used commands in an extension integrated into the software. You can build up a macro instead of manually executing a series of repetitive actions in Flux, which you will then be able to call regularly. A macro is interesting because it can encapsulate within a new command a series of repetitive operations and thus improve the quality and efficiency of the user-software interaction. Concretely, a macro file (*.py) is a text file, which defines the macro-function in the PyFlux language. It receives (upon entry) one or more parameters and executes (upon exit) a series of predefined actions. It is possible to use the macros provided with Flux or to create your own macros. All macros provided with Flux are open sources, to help you to create a macro fitting exactly your expectation. The list of macros provided with Flux is available in C:\Altair\Extensions\Macros\macros_list_EN.pdf. The moste recent one are described with more details in the attached document "New_Flux_macros_2016". New_Flux_macros_2016.pdf

  14. I want to simulate a geometry using Acusolve (AcuConsole) and I have a condition of mass flux for my outflow boundary, how can setup like this? The Acu Console only gives me the option of pressure values. Thank you.
