    Small equation pivot terms

    Yeah I know. I am supposing that the mesh is not correct as my system has not much memory (2 gb) and I am actually working with windows xp 32 bit. The dimension of the strucuture is something like 1000*1100*6000 (mm) so i have a lot of elements and if I refine the mesh the system tells me that...

    Small equation pivot terms

    Are u from italy too? However thank u fro your quick reply. In my structure the center of gravity lies on the axis on which pass the efforts so I am expecting no buckling. Is it correct to simulate the effect of the floor giving to the surface of the machine wich touches the floor a "compression...

    Small equation pivot terms

    Here it is the image of my simulation. Shot at 2007-08-10 The red arrow is the effort, the violet ones are the constrains (fixed support), and the yellow one is the gravity acceleration. I am still having problems with "small equation solver pivot terms". In the first run i've made i was...

    Small equation pivot terms

    Just to understand: the purpose of the test you propose me 'bout running a modal analysis is to understand if the If the modal analysis gives as an answer that one or more bodyes have frequency around zero it means that this bodyes are completely constrained?

    Small equation pivot terms

    Thank you for your reply. I Know that the message wb gives me is a warning and not an error, but the solution does not converge after at time 1 on 4 seconds so i am guessing that there's a problem on my model. I am going to run a modal analysis and i'll try to post some picture of my frame with...

    Small equation pivot terms

    Hi all. I a m running a static stuctural simulation on a simple metal frame on which there's a front load and a constrain on the back. As i am simulating ansys wb11 tells me that there are 5 small equation solver pivot terms. As far as I know it means that large displacements are going on in the...
