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

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...

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...

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...

Thanks for these clear and precise answers! It's exactly what I needed!

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...

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

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...

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...

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...

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...

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

Thanks, I didn't see there was a specific ANSYS forum ;)

ps : Im using ANSYS 11.0 and ProEnginner WildFire 3.0 ;)

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...
