There is no problem with reading this file. I see also pipe with two flanges, but the problem is that in model tree, under geometry I get two shells (instead of one solid). Please see the difference between two pictures I posted in my previous message.

So you get one solid geometry and you have femap version 11.2?
This is what I get with femap 11.2 (And it's not right)

And this with Femap 11.1.2 (this is correct)...
Hi,
Does anyone else have problems with importing step-geometry in new femap version 11.2?
I have tried to import this closed pipe (solid geometry) to new femap but result is two shells (inner and outer surface).
I also tried to import this same file to previous version 11.1.2 and it's working...
Hi,
Does anybody know is there a restriction for maximum number of lights in inventor studio? Everything goes smooth to light number 8 but after that lights have no effect. Sometimes I can get light number 9 on, but then light number 8 (or some other) goes off.

I got it now! I think the problem was that I forgot to save the data surface editor.
Thank you very much for help! :)

I already tried that. Same outcome :(

I check element normal vectors and those are correct.
I get error message "Unable to create 620 Load(s) on Element(s). Locations in Data Surface evaluate to zero or are outside the extents of the Data Surface." I tried to change all zero values to something else but it didn't help...
Hi,
Thanks for the excellent tips. I got the nonlinear pressure, but I have little problem with the distribution. When I expand the load it shows only on half circle. Is there something wrong with my data surface?
Pressure load...
I know I should use cylindrical CSYS and THETA direction to vary the load, but I don't know how to do it in practice.
Here is the function I have created (I think you can find my mistake here more quickly). X is angle in radians and Y is factor to multiply basic pressure. I think the problem is...

Hi,
I’m trying to model nonlinear wind pressure load on a cylindrical surface (see attachment). I think I should use cylindrical coordinate and function dependent pressure load. Does anyone have an idea how to create a function for this? Pressure should change in proportion to angle.

Hi,
Thank you Prex and TGS4 for your exellent answers! I think I got this now.
EN 13445-3 calculation is made like Prex stated because the formula is σij,l=σij,m+σij,b without any special requirements.
While in ASME there are requiremets: Bending stresses are calculated only for the local hoop...
Hi,
I thought that TGS4 meant that only hoop and meridional m+b components need to be summed
In my case YYm±YYb and XXm±XXb and other components are membrane components. With these two sets of six components I calculate m+b equivalent stress.
Prex- So you are saying that I have to sum all...
Hi,
Thank you for your reply. TGS4 – I didn't understand your answer because I didn't know that m+b summation must be made in component level. Now your answer makes perfect sense :)
Prex- Can you verify that this is what you meant.
Membrane:
Equal subdivisions: (n= 4 elements): dx/t =...
Hi,
If I have more nodes in SCL what would be common form for these formulas?
(s1+s2+s3+(s0+s4)/2)/4 --> (s1+s2+s3+…+sn-1+(s0+sn)/2)/n
Otherwise average of components except SCL first and last nodal values have been averaged. Is this right?
5-A.4.1.2 Step 1. … The membrane stress tensor is the...
Hi,
Thank you for your answers prex and TGS4. I got now two m+b value (38,13 and 25,85) but they are greater than total stress (linearization2.JPG). I know this is possible, but because I’m new with this I smell error. Total stress is calculated with equivalent stress formula in EN 13445-3...
Hi,
I’m doing excel tool for stress linearization and I need some help. I have six stress components for all nodes in stress classification line (SCL). I know the formulas are found in FAQs (http://www.eng-tips.com/faqs.cfm?fid=982), but I have hard time to solve these integral equations. I...
