    Problems with curve projection

    I am just trying to create a surface model of intersecting tubes, that can then be sent to a finite element package and meshed using quad elements.

    Problems with curve projection

    It’s good to talk Many thanks for your responses, MechatroPro - Using 'workaround' I want to try and keep the cylindrical surface as an untrimmed surface 'Another workaround' I tried that and the projected curve still projects onto the wrong side of the surface. SincoTC - You’re a star, I...

    Problems with curve projection

    Sorry my apologies, I presumed that the .ppsx could be opened in previous versions of office. Here we go Never used the Wrap function before. The curve is projected but it also trims the surface...

    Problems with curve projection

    Just wondering if anybody could help me. I am trying to project a line onto an extruded surface. To project the curve, I am using CURVE - PROJECT CURVE, then sketch onto face. I pick the curve and then pick the surface. In my case, the surface I am using is a cylinder, and there are two...

    Cross Sectional Area of a .stl file

    Many thanks, but i do not want to burden you with extra work. I will try and look at it myself and if i have any problems i will let you know. Thank you very much

    Cross Sectional Area of a .stl file

    CorBlimeyLimey - yeah that is a no rfus - I will have a look at the import point cloud and rhino. Many Thanks I am using Phoenics to calculate the drag, but i want the frontal area to have an estimate of the answer using some hand calcs. cheers

    Cross Sectional Area of a .stl file

    I have been importing it as a 'Graphics body' when I change the option to a 'surface body' I get an error saying "The STL model has too many surfaces - Please import this model as a Graphics body" I presume that my supplied model is generated with too many surfaces and I need to get the number...

    Cross Sectional Area of a .stl file

    Hello, I am trying to calculate the coefficient of drag of a couple of components. This is only a very basic CFD analysis that I want to undertake. To calculate the coefficient of drag, I would like to find the largest cross sectional area of the model. The models that I have been supplied...

    Meshing Areas within Ansys

    Mihajupb, Many thanks for your response the /facet,norm solved the problem. I use Patran on a daily basis but have to complete this job in Ansys. I only ever use the GUI commands really and never explored the use of command line interface. After the /facet,norm command the GUI PLOT>AREAS...

    Meshing Areas within Ansys

    Sorry to take so long but I have managed to sort the problem out. I have imported the problem as a parasolid, deleted the volume that is created in ansys and then used the left over areas to create a mesh. Now I need to start refining my mesh to increase the accuracy of my results. How do I...

    Ergonomics Standards - CoG Human Body

    Thank you very much for all who have offered me advice. I have looked mainly at the Nasa link (third one down on HamishMcTavish list of links) and tried to reference all my information from that research. However, bits of critical information are missing so I am going to make some assumptions...

    Ergonomics Standards - CoG Human Body

    Thank you very much to everybody that has replied. I have managed to find a document that has some positions of CoG and masses of major body parts, head, arms, torso and upper leg. The rest of the limbs I will just have to estimate. I have an understanding that the values will be different...

    Ergonomics Standards - CoG Human Body

    Hello, I am currently looking for a definitive standard that can be used in the creation of a percentile ergonomic model. I have found a NASA document that shows some of the lengths of various limbs, torso's and the suchlike. However I cannot find any reference to the center of gravity of the...

    Meshing Areas within Ansys

    Thanks for your response Alex, After looking at the help files, I presume that overlap looks at the two entities that you pick and then join's them similar to gluing but without removing the lines? However when I try and use the overlap function it comes back with an error message saying...

    Meshing Areas within Ansys

    I normally use Patran/Nastran for FE problems but have to complete this in Ansys. I have imported a surface model from Solidworks via IGES into Ansys and I am having problems gluing them together. Just wondering if anybody would be able to help me? From the little knowledge I have of Ansys...
