Hi i am trying to do a 3D fluid structure interaction of a transient dynamic problem using ansys multiphysics and CFX both v11 sp1. At the fluid structure interface i want to pass velocity, displacement or pressure information/data from the structure model to the fluid and once the next...

Hi I am using ansys cfx v11, i am a very recent user to this program so i am still learning. I am trying to set the contact angle and surface tension of water in a simple transient fluid analysis. However i cannot see how to set these parameters. Can anyone advise me on how to do this or even...

hi i am a new user to ansys cfx. i have used extensively ansys multiphysics and the 2d vof simulation. I want to extend my analysis to a 3d fluid problems. In my case "A droplet being ejected from a circular orifice on the end of a circular pipe" transient analysis pressure loading. I have...

does anyone have the conversion of microns cubed to picoliters? thanks

Hi I am trying to model a cantilever beam (mem’s scale). The beam is constructed from two materials; Aluminium layer (colour green) on top of a Silicon dioxide base layer, see attached database model. The element type is solid 45, (unsure if this is correct element type for this type of...

hi I am looking for tutorials for wildfire 4 including animation Can anyone recommend anything? V

Fluid flow through a rectangular pipe with a Elastomer membrane cap blocking one end. see attached figure Hi I am trying to simulate a fluid flow (i.e. water at room temperature) in a 3D square or rectangular pipe covered by an Elastomer membrane cap using Ansys MultiPhysics v11. Basically...

Hi I am using Ansys v11 SP1 on windows xp. I have two results file which I want to combine together. The first results file is over a time frame of 0 to 20 microseconds. The second is over a time frame of 20 to 40 microseconds. I wish to combine these two results files into one, and have the...

Hi I am trying to do a transient analysis of a double cantilever beam 9ie fixed at both ends) in Ansys MultiPhysics v11 on xp. The DCB consist of two materials, the first a heater material of aluminium on top of a passive silicon dioxide base. A square pulse voltage of 0.1 us seconds is...

I am unable to do a volumne sweep of element type solsh190 I can get this to work correctly can anyone give me a step by step guide Regards

hI I AM USING ANSYS MULTIPHYSICS V11 ON XP I WISH TO DO A TRANSIENT DYNAMICE ANALYSIS OF A DOUBLE CANTILEVER BEAM FIXED AT BOTH ENDS. BUT I DO KNOW HOW TO BEGIN. COULD ANYONE SUGGEST A GOOD TUTORIAL TO START WITH OR HAVE A GOOD SCRIPT / INPUT FILE AS AN EXAMPLE OF HOW TO DO SUCH A ANALYSIS...

Hi I have a quick question regarding Ansys running on windows 64 bit OS with 64 bit architecture dell pc. I am using Ansys MultiPhysics V11 64 bit on winndows XP . I wish to install the new service pack SP1 version of the software, released today, it too is 64bit , but I am unable to...

Hi i just installed the new version of Ansys Multiphysics V11 SP 1, 32 bit today. that went ok. Also installed license manager and selected and started sucessfully the license manager form the license file, so everything is ok there. However when i launch Ansys Product launcher it cannot...

I am using Ansys Multiphysics v 11 on windows XP 64 bit. It’s running on a 64 bit machine Dell 690 workstation. I am running a fluid transient 2D analysis over a 40 microsecond time frame. But every time the results file *.rfl reaches a size of 4GB the program crashes. I get the following...

Folks I am having problem opening an excel file. I get a blank grey screen when it opens with the file name of the document I have tried opening it in safe mode, repair using all online help I could find. Its really strange there is information within and if you open it with notepad you can see...

Hi I am having a small problem restarting a fluidic analysis. Basically I want to restart a transient fluid analysis. However when I do the restart I was to create a new *.db and continuing the analysis in this new database from the previous time step but write the remaining result to the new...

Hi I am using Ansys Multi-Physics v11 on windows xp. I saved a simple animation both as an *.avi and*.anim file format. The animation depicts a simple ale/vof analysis of a droplet of fluid moving through a simple 2D pipe. Not very complicated However neither animation will run externally...

Hi i have a graph of a displacement curve as follows i wish to get the derivative of it using excel. can anyone advise TIME UY_2 0 -2.58E-05 1.00E-02 -2.58E-05 2.00E-02 -2.84E-04 3.00E-02 -1.19E-03 4.00E-02 -3.17E-03 5.00E-02 -6.57E-03 7.50E-02 -2.60E-02 0.1 -6.53E-02 0.125 -0.12476 0.15...

Hi I wish to apply a sinusoidal A.C current of 1 Amp to a thermal electrical model using function editor. I am assuming the wave form is sinusoidal and takes the form of y=A*sin(wt+teta) A = amplitude = 1amp w =angular frequency teta = phase shift t = time I have never used Function...
