    Projected area CATIA macro VBS

    Hello, I'm trying to measure the projected area of a CATPART with respect to the three planes of the absolute reference system. Does anyone know how can that be done with a macro ? I know how to measure the volume and the wet surface with SPA workbench but not the projected surface... Thanks !

    Distributed load and BDF

    Actually I have found the reason why I couldn't do that easily : http://simulatemore.mscsoftware.com/properly-applying-loads-to-finite-elements-msc-nastran/ Do you know if there is any other way to find this distribution (using another card to define the distributed load or something like that) ?

    Distributed load and BDF

    Hello, I think that this make no sense because the force in the BDF is one order of magnitude higher than the Max force I applied (3000N). The first image show the force per line (I used a Distributed Load). If I make the numbers as you said, I do not obtain the same results that there are...

    Distributed load and BDF

    Hello everyone, I would like to apply a variable distributed load to an edge of my model, something like this : When I do the BDF the force is moved to the nodes but the problem is that values are not coherent at all : If I want to make my own BDF not using Patran, how can I find this...

    Plate Buckling coefficients

    Hello everyone, Does anyone know how can I obtain the equation of the buckling coefficients for a composite plate ?. I want to know the function of this kind of chart :

    Logarithmic Strain

    Ok, understood, but there is no way to compare the strains between a linear model and a non-linear model?

    Logarithmic Strain

    And why Abaqus do this? What are the advantages?

    Logarithmic Strain

    Is very close, yes, but the problem is that I'm trying to compare two models and I can't if I only can obtain the LE instead E

    Logarithmic Strain

    So, if I well understood, if I use non-linear geometry it's impossible to show the E ?

    Logarithmic Strain

    Hello everyone, I'm trying to obtain the strains from a model. I request the "E" variable into the .INP in order to do so but what I found into the ODB is the "LE" (logarithmic strain). Does anyone knows why? Is there anyway to change between them mathematically?

    Free Body

    I have my beam that should have a moment of 7.5e3 et now I obtain 6.0e3 in FEM. Does anyone knows what's happening? I have already checked the reference system, the point and lever-arm are both OK...

    Free Body

    Hello, I’m trying to find the free body loads of a beam but when I do a simple verification the results are not OK. What I obtain from hand-made calculs are not the same as FEM show me. For example, I should obtain a moment of 5.0E3 and in FEM I obtain 4.385E3. why?

    RBE3 Abaqus

    Hello everyone, I'm looking for the equivalent to a Nastran's RBE3 in Abaqus. As far as I know the 'Distributing Coupling' should be the same but actually what I obtain is only a distribution of the applied load in the master node to the slaves nodes (and that was not supposed to happen with...

    FreeBody

    Actually, just to see what's happening I've made a quite simple model: a box with an applied load in one side and a encastre in the other one. I cut the box just in the middle, I plot the FreeBody Loads by components and, as expected, I see the resultant load in one of the axes that corresponds...

    FreeBody

    Thaks for you help StefCon! Yes, I'm using a free cut with a plane and as you said it's normal to find some errors in the results. The problem here is that I'm finding errors one order of magnitude (even two!) higher or lower so something strange is happening...
