    heat transfer in mechanica

    Hi tonz1984, How about the boundary conditions? If I understand good your heat sink should exchange heat with the boundary (open air or cooling system), and the Thermal Analysis ends when it gets a heat balance. As far as I know in order to perform a Thermal Analysis you have to provide a load...

    Mechainca FEM to Normal Analysis

    Hi Slamdfullsize, Try the following: Open your part and move to the MECHANICA module. From the menu select "EDIT" and then "MECHANICA MODULE TYPE", you should get your "asking box" again. You can now de-select the FEM mode in order to analyse your model by ProMechanica Native Solver. hope to...

    Flow Works Boundary Conditions

    Hallo Cylo, I'm using FW 2004 since some years. I ran up against the same error message "Face <1>@Lid-1 is not laying on the boundary between solid and fluid region", when I erroneously selected a surface of the lid not contiguous the fluid region, or when the computational domain was no set as...

    Floworks: streamlines passing THRU solid :(

    Hi, If I understood correctly your analysis has been correctly completed by the solver and you have a problem with the "Cut Plots" overview, am I right? I'm using FW 2004 and last year I had a similar problem working with a Flow Internal Analysis across a valve in a pipe. After performing a...

    Floworks: Surface Parameters for a valve disc (torque calc.)

    HELLO TO ALL! In order to calculate the torque (given from the fluid) on the disc surface of a valve that lies in a piping, I have selected the function "Surface Parameters" in the Results Menu, but I got some unexpected results about the "Integral parameters". Particularly I need some...

    reality check

    NrM, I'd do a Contact Analysis in this way: 1.Fully constrain the Tote 2.Apply the Force load to the Plate in axial direction 3.Constrain the Plate in the directions different from the axial one (you should use Cylindrically Coordinate System and lock the radial and tangential directions)...

    reality check

    NrM, Do you mean you have to study the behaviour of a plastic tote subjected to a pressure load? Or do you have to simulate contact between the two parts (plastic tote and metal plate)? Regards!

    Post-Processing Time

    ahad, I hope this information about control number of elements (in INTEGRATED MODE) could be usefull, I took this information from PTC Knowledge Base Site. Suggested Technique for Preparing Model In Pro/MECHANICA Structure and Thermal, elements need to be generated in the part or assembly as...

    Post-Processing Time

    Hi ahad, I am using Pro/Mechanica 2001 structure module too, and my experience about Static Analysis brings me to analyse models with no more than 7000 elements using the maximum degree polynomial, because calculation and post processing time become unacceptable (and sometime the program...

    Pressure load in a cylinder

    fsison, The easy way to create a surface region into a cylindrical surface, as far as I know, is the following: 1)Move on FEATURES menu and select the following options : SURF REGION --> CREATE --> SKETCH --> DONE 2) Pick a plane through your cylinder axis (you should see your cylinder axis...

    Pressure load in a cylinder

    Hi fsison, You could create a surface region, as big as you need, inside your hydraulic cylinder (go on STRUCTURAL / FEATURES Menu) and then you can easily apply the pressure load directly on that. Regards!

    thread teeth analysis

    Hi anny, I have to perform a similar analysis. I followed RocketRonnie advise and I got some interesting results in comparison to our expectation. My only uncertainty is how much the initial gap I had to give to the 2 parts (nut and bolt)of my assembly can affect the final results? Did you...
