Multiple Loads/pressures/gravity in hypermesh

Hi,

 

I cannot find clear tutorials or topics about how to apply multiple loads on a model.

I need hydrostatic pressure, gravity, and multiple point loads.

Anyone able to help?

 

Best regards,

    Same type or same purpose loads are grouped into a load set (load collector)

    Load sets are combine by load collector 'LOAD' which refered by loadstep

    Every tutorials guide that, dont you see?

    Hello,

     

    What type of analysis are you trying to do?

     

    For multiple loads, first as said you need to organize the same type of loads in a single load collector then create a loadstep to combine the different types of loads. The type of loadstep will depend on the type of analysis you are trying to do.

     

    Thank you

    Hello,

     

    Thanks for the reply!

    I have this bow section of a ship and need to add constrints, hydrostatic pressure, extra pressure due to sailing, wave loads, self weight (gravity), component point loads (machinery), and forces (torsional and bending moments) due to movements of the vessel.

     

    I think I have to organize individual load collectors for:

     

    -all hydrostatic pressure and additional hydro pressure + wave loads

    -gravity self weight

    -components point loads

    -torsional and bending moments

     

    Is that correct? 

     

    And when creating loadstep, do I have to choose the same constrainst in every loadstep?

    And how to choose what type of loadstep for the different analysis?

     

    Thanks a lot in advance,

     

    best regads,

     

    Joep

    Hello,

     

    After creating all the loads you can combine all of them into a single 'Load collector' whose card image should be 'LOADADD'.

    S1 is the scale factor.

     

    Select all the loads in this load collector.

     

    Then i think you can do a linear static analysis. In that reference the constraint and in place of 'Load' reference the 'LOADADD' load collector.

     

    You can reference the following type of loads in the 'LOADADD' card.

    You can also refer the help section for more information.

     

    Thankyou

    And if you have TLOADs?
