  1. Hello everybody, my name is Thomas from Germany and I am working on my Bachelor Thesis, which is about the topic CFD, at the moment. I am at the beginning of my Thesis and at first i want to create a simple model validation. My topic is about an easy Venturipipe, which gets passes through water. So there are only two variables, which are important: The pressure and the velocity, which i estimate with an analytical calculation, too. The Venturipipe has got a rejuvenation. And if you think about the Bernoulli´s equation, the velocity gets higher and the pressure goes down near the rejuvenation. When the fluid leaves the rejuvenation, the values supposed to be retransform back to the input values. And the model gets unrealistic at this point: When the fluid leaves the rejuvenation, is does not get slower. I create the model data with HyperMesh 13.0. Unfortunately i am not able to find any mistake in the input file, which is computed with AcuSolve. I hope that someone will hear my problem and is able to solve it. Probably there is only a little mistake, which destroys the complete model in the end. Thank you for your support in advance! Best regards, Thomas PS: There is a zip.file enclosed, which includes all the important data and some results, too. Venturi_Pipe_Problem.zip
  2. hello.. any one can tell me in detail how to do this process below i’m stuck in AcuSolve workshop 4 Blower – Sliding Mesh and I have a problem every i finishing runing acusolve transient analysis, can't open the result in AcuFieldView, always error to open it regards
  3. AcuMeshSim can be run in a batch mode such that users can set up their meshes using AcuConsole on a laptop or desktop machine, then use a different, large memory machine to construct the mesh. This is accomplished using the following process: 1.) Set up the meshing controls using AcuConsole 2.) From the "Launch AcuMeshSim" panel, enable "Export ams file", but disable "Launch AcuMeshSim". This will write all of the necessary input files for the mesher (CAD.DIR and <problemName>.ams), but will not launch the mesher. 3.) Copy CAD.DIR and <problemName>.ams to the machine where you want to build the mesh. From the directory where these files reside, execute the following command: acuMeshSim -pb <problemName> 4.) Once the meshing completes, copy <problemName>.arm and MESHSIM.DIR back to your local system and load the mesh into AcuConsole using File-->Import. Be sure the file type filter is set to .arm.
  4. I load my .x_t parasolid file for the geometry and then get the next error: Traceback (most recent call last): File "pnlFile.py", line 323, in importFile File "pnlWin.py", line 1440, in readData File "pnlImport.py", line 178, in readData File "pnlImport.py", line 294, in readDataFile File "pnlLoadGeom.py", line 264, in __init__ File "pnlLoadGeom.py", line 293, in readGeom File "pnlLoadGeom.py", line 357, in loadGeomData File "pnlLoadGeom.py", line 742, in readCad File "pnlLoadGeom.py", line 1746, in saveGeomTree File "pnlDb.py", line 731, in putStrPar File "ahdBase.pxi", line 733, in acuhdf.AcuHDF.putStr File "ahdBase.pxi", line 2449, in acuhdf.AcuHDF._put File "acuuc.pyx", line 79, in acuuc.toStr File "/home/acusim/p4_acusolve/acu_r12.0/linux64/base/lib/python2.4/encodings/utf_8.py", line 16, in decode UnicodeDecodeError: 'utf8' codec can't decode bytes in position 8-11: invalid data Traceback (most recent call last): File "pnlFile.py", line 323, in importFile File "pnlWin.py", line 1440, in readData File "pnlImport.py", line 178, in readData File "pnlImport.py", line 294, in readDataFile File "pnlLoadGeom.py", line 264, in __init__ File "pnlLoadGeom.py", line 293, in readGeom File "pnlLoadGeom.py", line 357, in loadGeomData File "pnlLoadGeom.py", line 742, in readCad File "pnlLoadGeom.py", line 1746, in saveGeomTree File "pnlDb.py", line 731, in putStrPar File "ahdBase.pxi", line 733, in acuhdf.AcuHDF.putStr File "ahdBase.pxi", line 2449, in acuhdf.AcuHDF._put File "acuuc.pyx", line 79, in acuuc.toStr File "/home/acusim/p4_acusolve/acu_r12.0/linux64/base/lib/python2.4/encodings/utf_8.py", line 16, in decode UnicodeDecodeError: 'utf8' codec can't decode bytes in position 8-11: invalid data I tried reading another geometry file also x_t, and it worked. So I guess there is something wrong with my file. From the error I posted above, can we know what is wrong? Some kind of setup problem, encoding?
