    Metric thread ASME plug

    @jmec87, thank you very much for your reply. When you say that our plugs must meet all the relevant requirements, what exactly do you mean? Where may I find the relevant requirements? Thanks again, we are really desperate and any help is very much appreciated.

    Metric thread ASME plug

    Hello all, We are working on a project for a plant at British Columbia (Canada) and we are really struggling due to CRN restrictions. Our biggest problem right now is that we have an ASME VIII Div.1 pressure vessel (235psi @ 400ºF) with a M18 P1,5 female thread port which we need to "plug"...

    CE marking - Pressure Vessel Supporting Structure

    Hi there, I would like to know if the supporting structure of a pressure vessel can be included in the CE marking of the pressure vessel itself (by including it in the design), or if there is no way to include it. In case it can be included, does the structure need to be permanently joined...

    SOL 101 and 103 run perfectly, but SOL 105 gives excessive pivot ratios

    So guys I think I found out why I get the Max Ratio fatal message. I forgot to specify the SPC for the two buckling SCs. Thanks a lot for your answers, [2thumbsup]

    Hi nlgyro, The DMIGs are a requirement of the customer... Why do you mean by the relevant sections? What exactly do you want me to post? Thanks in advance, Jose

    SOL 101 and 103 run perfectly, but SOL 105 gives excessive pivot ratios

    No, the constraints are exactly the same. Only one Subcase has temperature and the other one doesnt. I upload both Input Decks, maybe it helps... SOL 101 SOL 101 CEND ECHO = NONE $$------------------------------------------------------------------------------$ $$ Case Control Cards...

    SOL 101 and 103 run perfectly, but SOL 105 gives excessive pivot ratios

    Hi hezhj200, Thanks for your reply. So the first 2 frequencies are around 11Hz, the 3rd is 89 Hz and the tenth is around 190 Hz. I don't understand your possibility, could you re explain it? I have exactly the same loads on both calculations. In the SOL 101 I have SC1 with the SOL 105...

    Define two load cards in for one subcase.

    Hi dwallace1971, Thanks for your reply, It's a linear analysis. SOL 101. I have seen in the manual it can be done with SUBCOM, but this involves also quite a lot of work to do. I have the LOAD IDs already defined, I just have to be able to add two different LOAD IDs to the SUBCASE. SUBCOM...

    Define two load cards in for one subcase.

    Hi, I need to ask for two different LOAD cards in one subcase calculation. I tried separating them by commas and putting them in different lines (like shown in the following code) and none of them worked. I really need to define it separately because I have like 200 subcases and if I merge...

    Change Patran default nastran input offset

    Hi aznar, Thank you so much for your reply! I tried what you said and, as you said, it is not working. I just figured out from the link I posted that the command db_import_auto_offset is used to disable auto offset when importing a Patran database. Since I want to aply this when importing...

    Change Patran default nastran input offset

    Hello, I am looking for a way to change the default setting of Import/MD Nastran Input Options/Define Offsets/Offset from the value "Auto" to "None" or "0". I searched the web and the only helpful bit a read was about changing the environment parameter: db_import_auto_offset in the following...
