I need to create a local reference system applied to a two elements beam rigid body. I tried the command *TRANSFORM but the user manual writes as follows: “The transformed coordinate reference systeme system is always a set of fixed Cartesian axes at a node (even for cylindrical or spherical...

hi akabarten, thank u so much for the help. I've never seen this keyw. I'll study it and try to apply to my model, in fact a local coordinate system make it easy for the step I mentined in my first thread but on the other hand it's more complicated to write BCs for the step before the one I...

Hi, In my model I have a part that is a beam meshed using pipe elemnt. As showed by the figure in attachement I need to apply a boundary condition that restraint the movement of the node N2 in the transversal direction with respect to the beam axis (i.e. along the axis 2'). Global axes in my...

hi guys, regarding the information given in thread 799-196031 I'd like to know if I need to download the activestate or Enthought distribution or it's enough to dowload the packages following the links given, for example, at the web site http://www.scipy.org many thanks

Zisis as far as I know 32bit OS does not allow u to allocate the large amount of RAM that u have in your PC (40Gb). In particular, please correct me if I'm wrong, u can allocate (use) only 2^32 that corresponds to about 4Gb with 32bit OS (then u have to subtract the memory amount needed for the...

Hi DanStro thanks for your advice, but it doesn't work. As far as I know the append method is available in array module. I've imported the array module and tried your solution but it seems that a.append() require a float as input in brackets therefore u can not give [9,10,11]. As said previously...

Hy guys, I need an help on how to manipulate arrays in python using the module Numeric or array. Consider the following array a a = reshape(arange(9),(3,3)) >>> print a [[0 1 2] [3 4 5] [6 7 8]] ok, now how is it possible (any command?) to add a new row let say [9,10,11] to the array a in...

Hi akabarten thanks for your help. With your advice I solved the issue. Bye bye

Hi guys, I'm reading the obd file to postprocess an analysis. The point is that, in my python routine, I would like to create a node set that I did not create in the preprocessing. In this way it is much easier when I extract the results from the fieldOutput. How is it possible? thanks in...

Hi, as regards the second issue I got around it simply putting in the same file .for the two subroutine and calling this file in the command line when submitting the analysis. As regards the first issue I realise that I can retrive nodal coordinates also with the function DISP but at the end of...

Hi guys, I want to write a simple subroutine that gets the coordinates of a node (i.e. 10600, see attached file) and, at the moment, writes them in a text file. Generally I start with simple exercise for understanding how to use, in this case, the function GETVRN. My question is, as far as I...

I got around it. I fix the problem using suitable connectors element to link the nodes of one rigid body to the corrispondent of the the second rigid body in order to achive the system configuration given in attached files. Reading the documentation I figured out that the error with...

Hi guys, I have some difficulties to constraint the displacement DOF of nodes 1 and 2 (see the attached file) to the correspondent nodes 3 e 4 (in the figure the rigid body RB3D2 is shifted in order to make the nodes to be visible, actually the nodes are superimposed i.e. have the same...

Hi guys, I had some problems in understanding the rotation output field in the viewer. Therefore I gave a look to the doc., in particular I'm referring to the user manual section "1.2.2 Conventions". At the end of the first example (i.e. 60 degrees about z-axis, 90 degrees about beam axis and...

Hi Gatre, I'm not very used with CAE so my advice, even if it may seem rough, is to make the CAE to write the input file. Edit the .inp file and find the rows where the material specs. are written and then just use the option to give the material charcteristic s-e curve through a text input file...

Hi, got around it, using the assignin and evalin I solved the problem storing the data in the base workspace and extrancting later on when I need them. Bye

Hi guys, I have to plot a serie of data (x,y) that are read from a text file. How can is it possible to store the data in a variable in the workspace in order to make it possible to access/process the data after each action (for example after pushing a button etc. etc.) without reading the txt...

Hi potf, yes u are right. I read only the overview and so I missed that one....always read till the end of the page!!:-) Thanks a lot guys Bye

Hi guys, thanks for the answers. Actually I'd like to avoid so complicated procedure using restart....therefore at the end of the day no user subroutine for the scope to impose directly the step increment :-( See you

Any suggestion guys? Bye
