Which version of the software is this ? 2020 or earlier ? I once had this problem where I had created a model with Metric/Metric unit system. Then later when trying to edit I had a metric/inch system set and could not edit the model. Setting it bac

Yes that is correct. FEATools (the full licensed version) is more advanced than B31J. B31J implements empirical equations (based on testing and FEA results), while the full FEATools also includes full finite element analysis of tee components.
CAESAR II
B31J SIFs are not applicable for torsional branch loads. Since torsional branch loads on a lateral connection act on a thin oblong opening, better to use FEATools as it automatically calculates the torsional SIF and incorporates it into the model.

I opened up one of our tank models and I can no longer modified it. Nozz. list as 3d objects and all data is there when I hover over nozz. But I can not add nozz or edit existing nozz. The equipment pallet does not open when double click on equipme

THANKS A LOT BORZKI AND RICHARD SIR FOR YOUR HELP ON THIS ISSUE

I believe the catalog level custom data can be set as a default, but can be overidden in the model with different data

It would be quicker to email Tony Paulin over at PRG.

Thanks dan. actually when I google it, I found many technical articles related to this. Anyway, I'll just cross the bridge when I get there. No real job of this sort at the moment. Just preparing myself in case I encounter one. Cheers!!!

Better write to the committee and clarify. Warm Regards,

I will look into the suggestions here. We looked at just adding Custom Data on the data table for valve. However, it was then an issue with inside the same spec, we would be linking to that same data table and needing two different operators and valv

THANKS ALL FOR YOUT TIMELY HELP However i am still not sure for applicability of B31J to only 90 deg branches due to the below statement in 31J. Any views on the same?

Have you looked at using Custom Data ?

Sometimes will be labeled as Special Piping Item, but you will still have to buy as it would be an equipment item I guess. Sometimes it is necessary to have the calculations as you specified due to thermal gradient, but again, this is a very narrow f

Thanks Dan for clarifying. I thought it was a piping component that is the solution for this high thermal gradient between two streams. If anyone has a picture of it, would be nice to see it. But if it's proprietary and not for public use, please

The mixing tee is not a piping component. It is an inline element with inlet/outlet and a side connection for the fluid that will be mixed with the main fluid. There are some non moving blades inside that help mixing the two fluids. I guess it is not

Hello, fellow Stressers!!! Have anyone have experience in mixing tee design. Just curious how does it looks like. Just heard of it but haven't seen one. This is one solution, depending on the outcome of CFD coupled with thermo-mechanical analysis.
CAESAR II
Michael is right. My senior stress engineers before just use 2 x SIF of 90 deg. since FEA during that time is scarce if not available. With the tools available now, it's better to use it and compare it to 2 x SIF of deg. Physical testing is anothe

Index and Dat Codes should do what you are after, but it needs to be a full long description based on the index code. If you are looking to build a long description based on many different fields, then you can add the fields to one of the required ta

B31J was an enhancement to what's already within B31.3. Neither cover branch connections outside of 90 degrees.

I have a client that is wanting as much information as possible to be added to the long description of several components. I will use the valve though as an example. Is there a way to add a custom table for the various valve trims and then reference

Hi Borzki thanks for your response. I had an additional query if i do not have FEA tools enabled , Still i suppose we can use B31J utility of C-II FEA Translator for D/d < 50 and d/D 50 and d/D > 0.6 does B31J allow these options or do we have to
