I am updating one of our old FEA models (that used the legacy SOLID45 elements) to use SOLID185 and in the process I noticed that the integration point principal stresses available via ETABLE (NMISC) are no more available for SOLID185. Is there a way to access those integration point stresses...
Hi,
I am new to vacuum technology and recently confronted with a problem of polymer seal design for a vacuum application. I am calculating the permeation rates of various gases through polymers.
After going through some handbooks for permeability coefficient values of gases for polymers I am...
Hi,
I am trying to solve an air permeation problem through a polymer seal but i don't have any experience in vacuum technology. I worked on this problem a bit but not sure if my approach is correct.....
Let's say I have a cubical Glass vacuum chamber (volume V) with initial high vacuum...
Hi,
Here is a simple permeation problem I am trying to solve but confused with the calculations
Let’s say I have a cubical Glass vacuum chamber (volume V) with initial high vacuum about 10-5 torr. (No more pumping to maintain this constant)
The chamber has a rectangular seal of area 'A'...
Hi,
We have ANSYS/LS-DYNA license and i can generate a the LS-DYNA input file (*.k) by using "write jobname.k" option in ANSYS GUI (under solution). I can solve this separately using LS-DYNA executable as we have a separate LS-DYNA license. However when i Issue the SOLVE command with in...
I have True-Stress vs True-Strain data from tensile test experiments. this data has more than thousand points(x,y) to totally define the stress-strain curve starting with the initial linear elastic response followd by plasticity (hardening) till necking.
Now the questions are
(1) Do i need to...
Is there a command/macro to offset lines in ANSYS? By OFFSET i mean the keypoints should move normal to lines to the specified distance. I know LGEN works for straight lines and circular arcs but what about other irregular curves? (Its cumbersome to find the centers of every segment and use...
Is there an easier way to group the the newly formed lines after the command LDIV? Assuming the original lines have some attributes assigned using (LATT).
Lets say i have a set of lines grouped using CM command. Now i split some of the lines in this set and want to regroup including the newly...
I built a simple thermal model in ansys which is just a 2-d recangular area. The model runs fine and i get a nice distibution comparable to closed form solution when i specify temperatue BCs (Type I: D,all,temp,xx) at all the edges. However, i run in to HT FLOW CONVERGENCE problem when i change...
Hi,
I am trying to model a turbine blade for which i would like to represent the profile as accurate as possible. I have an eqution for the blade profile to get the vertices. I would lke to generate some kepoints using profile equation and want ANSYS to genrate a smooth curve (atleast...
Is there a command in ANSYS to generate a line from a given key point that is tangent to an existing cicular arc (or say another line)?
Thanks,

I have a problem where i am modeling a cylindrical (steel) bar embedded in concrete and i am trying to smulate shear test. For this case I have some doubt regrading designation of contact and target surfaces. As per ansys contact technology guide the following applies
3.5. Designating Contact...
I have a worksheet containing a column with time in HH:MM:SS format and formulas in other columns. I want to print the worksheet with formulas for which i did Options->View->Formulas.
However, doing this changes my HH:MM:SS format to some number that i dont want. when i turn off the view...
Is it possible to use subscripts/superscripts in excle plot legend titles. I can do this in the axis titles but excel is not allowing me to do so in legend titles.

I am very new to valves and pumps stuff and need some help choosing a valve (with actuator) for one of our experiments. Following are the requirements
1) Application: liquid (Water) flow control
2) Fast opening (Fraction of a second (<0.1sec preferred)).
3) Size: 3"
4) Pressure: Max 500 psi...
My drawing contains a number of lines with different thicknesses(weights) but when i print it out i am getting lines with same thickness (Its making thicker lines to thinner). Is there any setting in solidworks options to get thicker lines in printouts (either hard copy or pdf file). It doesn't...
Is is possible to hide construction line in drawings? I have a drawing that is symmetric about a centre line (for construction) . Now i want the print out not to show the centre-line. How can i do this?
I tried to give the centre line same color as background which avoided this line but the...
Is there a way to save the the model as image files (JPEG, tiff) etc when we are using 2 or 4 view in solid works apart from using print screen button ?
when ever i try to save the figure as jpeg files (file->saveas), its only saving the Active window but not all the views.

I have a surface body and i want give some thickness to this on both sides so that the existing suface forms the midplane/mid section) of the resulting solid part. How can is do this in solidworks?
Also when I try to look at the section view of my surface part, solidworks reverts back the view...
Is it poosible to sketch over a cylindrical surface in solidworks? My problem is, I have a part that looks like a circular belt in top view, and the whole part seems to be deformed over a cylinder when viewed from side Imagine a circular belt placed over a cylinder). How can i model these kind...
