If you do: Plot/Redirect plot/To jpeg You'll get picures in a file with background colour changed into white and text into black Best Regards

Hi everybody! I'm trying to calculate the SF as SF=Allowable stress/Von Mises stress. I define a Element Table for SEQV stress and and I label this table as SVM. I calculate SF as follows: SALLOW,500e6 SFACT,1 SFCALC,SF,SVM,,1 Next, I plot SF element Table. However, minimal SF calculated...

Hi everybody, Something very simple I'm sure you can solve it very easily: How can I change legend text color? I can´t find the option in the plot controls Thanks very much Enrique

Hi everybody, I'm trying to create a BEAM element by meshing a line. I have BEAM44 (and other types like PIPE16 or COMBIN14) defined. Code I follow is: SECTYPE,100,BEAM,I,p1 SECDATA,VAL1,VAL2,VAL3,VAL4,VAL5,VAL6 SECNUM,100 LMESH,number of line to be meshed /ESHAPE,1 /gline,1,-1 The problem...

As the other posters, I have always used NASTRAN to apply static thermal loads (a Thermal boundary condition) in structures in order to study deformations because of a thermal gradient. The problem is how to get these thermal boundary conditions. I know you can solve fluxes with NASTRAN nbut in...

Hi Gbor, Thank's to the point you gave I have solved the problem. I'm using NASTRAN 2005. I should clarify some other conditios of the problem: samples are isostatically restrainted and cores have different E,G but same CTE in three orthogonal directions. The main doubt I couldn't clarify...

Hello again 40818, Thank's very much. Anyway, is there any difference between VMOPT,1 and VMOPT,2? That's the only point it is not still clear to me. Best Regards, Enrique

Hi everybody again, I'm trying to understand the difference between two parametres related to calculating resonance frequencies in a modal analysis. I'm doing a modal analysis of a wetted structure. The fluid is air. Three optional parametres can be chosen: "PARAM, VMOPT,1","PARAM, VMOPT,2"...

Thanks for your answer 40818, But as you said, maybe you had too much wine. An orthotropic material can have different CTEs in each direction...That's one of the differences with isotropic materials. There are some others that can be found at basic engineering books. Calculation of expansion...

Hello, I've been working on simulating two numerical samples in solid elements. Both samples are in different materials that have the same Coefficient of Thermal Expansion (CTE)in three directions. In addition, a thin skin of shell elements in aluminium (with a CTE different from the one of the...

Hi everybody again! Asking for STRESS in Nastran gives you back stresses in each ply of an element which property is a PCOMP card and you can see stresses in each ply at the .f06 file. However, when I import the .op2 file in I-DEAS and try to visualize ply stresses, I-DEAS show you just one...

Hi everybody! I'd like to know hot to visualize in IDEAS a temperature map asigned to the model in a coloured scale by using the TEMPD card Thank's very much

Is there any way in Patran to combine solid elements in patran as it is done for shell elements (Utilites/ FEM Elements/ Combine Quad-Tria Elements)?

Hi Everybody! We're having a doubt about MFLUID CARD. You define in it the Coordinate system and the position(along Z axis of this CS) of the free surface of the fluid (ZFS: every element which is below ZFS is wetted). If ZFS=blank, the default value is ZFS=infinite. My question is if, in this...

Hi everybody! I explain you my problem: I have two Coordinate Systems, a global one and a local one. I define a node and I-DEAS ask me the coordinates of this node. Even when I define the node referenced to the local System of coordinates, I-DEAS consider this coordinates referenced to the...
