    free meshing software

    Hi everybody, Im looking for a free meshing software which could generate .cmdb files. Does anybody know a good one ? Im currently working on heavy CFD models (over 2 millions elts) and both ANSYS meshing and CFX Mesh cant give me accurate solution. Thanks by advance for your inputs! Regards, Tom

    eZdsp F2812 & MatLab -> Brushless DC motor

    Hi everyone, In order to design a controler for a Brushless DC motor (3 phases trapezoidal with Hall Effect sensor), I need some information about the DSP controler "eZdsp F2812" (Texas Instrument C2000 Series) and especially how to program it in MatLab/Simulink. I am a newbie in this specific...

    damping ratio sand

    Hello everybody, Here is my question, is is possible to define a kind of "damping ratio" for a defined volume of sand ? Im working in a lab and we would like to use sand mechanical properties to damp vibrations from the floor which are transmitted to an instrumented motor. Thanks for your...

    how to generate Gcode (CNC) using proE widfire 3.0

    Hi everyone, I am looking for tutorials concerning the generation of Gcode programs (for the CNC machine tools) using ProE wildfire 3.0 . Is is something hard to do ? If some of you are used to do it, maybe a step by step explanation would be enough as well! Thanks by advance for your inputs...

    creating/assigning material in ProE wildfire 3.0

    Sorry for this question which is certainly very basic for most of you, but I am novice at ProE and I have to train by myself... So here is my question, what should I do to create and assign materials to parts in proE ? The second question would be where could I find the mass and moment of...

    "external" torque sensor

    Thanks for all these valuable inputs ! We finally use a motor housing flexibly mounted and piezo/strain gage sensors to measure the deflection. Thanks for your contribution to this very helpful and professionnal forum ! Thomas

    rolling cylinder on plate

    Hi everyone, I'd like to model a rolling cylinder on a plate. I tried to use the contact region tool but I'm not sure if it is the good way to do this... Basically, the cylinder should just roll on the plate, in other words I'd like the rotation and the translation of the cylinder to be coupled...

    "external" torque sensor

    Thanks for these very interesting links but as you said I'd like to avoid the use of inline unit because of the lack of the accessibility of the shaft and these solutions look, as well, a little bit too expensive ;) " I've also heard of using gear teeth and prox switches to measure the shaft...

    "external" torque sensor

    the motor weights approximatly 25kgs, dimensions 15cms*15cms*25cms... the solution with the arm/calibrated weight or load cell looks interesting but I am not sure it would be accurate enough regarding the accuracy I need !( <0.005 Nm) I'm looking for 'external' sensor because I'm afraid the...

    &quot;external&quot; torque sensor

    Hi, here is my problem: I'd like to measure the torque produced by an electrical motor very accurately. (accurate<O.OO5 N.m) The point is: I'd like to use an "external" sensor and not a classic axial torque sensor. I've tried to use piezo electric sensors, in order to measure the reaction...

    ANF File - ProE parts import

    I ve finally copyed the "proe1.bat" file in the ANSYS working directory (where the proE files have to be!!). It has fixed the problem ! Thanks for your answers! Tom

    ANF File - ProE parts import

    hello, I am trying to import a ProE assembly into ANSYS in order to do a modal analysis. But I have an error message “File jobname.anf does not exist”, I have found this topic http://www.padtinc.com/epubs/focus/common/focus.asp?I=5&P=article2.htm but it doesn't fix my problem... I have also...

    ANSYS modal analysis

    Hello all, I am currently working on a modal analysis of an electrical motor IN USE. I can only use ANSYS to do it, what is the best way to do that? I had a look to ANSYS'help, but only found modal static analysis (only possible loads=displacement with the module "modal analysis"...) or...
