    Pneumatic air test force

    Hi, Is it possible to determine the force behind a 300dia cap end (blank) when undergoing a 0.5bar pneumatic air test and subsequently how far the force may move the 16kg cap end? The volume of air can be estimated. Thanks

    Matlab and Ansys

    Hi I am trying to perform non linear optimisation that requires interfacing between matlab and ansys. I have learn't from ansys guides how to start ansys using a batch file which i can run from matlab but what I don't know is how to alter variables for the ansys run. The optimisation is the...

    Best way to draw

    Hi, I have drawn the shape below. http://i423.photobucket.com/albums/pp315/skaboy607/Uni/heat_exchanger_halfinch_2.jpg I drew it using the line tool and then applying the desired radius I require of 38.1 mm. I then used the 'tube' tool to create the shape with required inner and outer...

    Helix Amendment

    Hi, I have drawn using the helix and tube tools a copper coil for heat transfer-see image below. http://i423.photobucket.com/albums/pp315/skaboy607/Uni/coiltst_2_2.jpg What I would like to do is extend the start and end points so that I end up with this-see image below...

    Batch cooling with an internal coil

    Hi, I am looking to size a copper coil to cool a volume of water by 5-10 degC. I have found numerous examples for heat exchanger calculations. The volume of water does have an inlet and an outlet but it is very slow so should this be treated as a batch cooling problem (think this is how they...

    Need a pump that satisfies these conditions

    Hi I need a pump that satisfies these criteria. I need to pump water at volume flow rate of 0.6 l/min. Pressure in the system to overcome in just over a 1m. I have a pump but it has a max flow of 16 l/min and although it is linked to a valve, I feel that would I have to restrict the flow...

    NX Import

    Hi I have been trying to import a .dxf file. The initial import is fine and I then save it as a .prt. However when I add this to my assembly which is dimensioned in mm, the part is tiny compared to everything else. When importing the .dxf I have changed the default system from mm to m to...

    Circular Array

    Hi I want to produce an array of 6 circles around 360 degrees. I have tried using the instance feature but that didn't work for some reason. Under instance geometry I am not sure what options to choose to produce this array. I am using NX 6.0. Any help much appreciated. Thanks
