Mesh can't be created

The recommended element size is to have 3 elements by the width of the part.

The wall thickness  of the part is 4.5mm so I need an element size of 1.5 mm

When trying to do so I get a message of too many elements, 23.16 million elements.

(23.16 )*4.5(GB)= 104.22GB (Ram memory needed)

I have 128 GB Ram memory. 

Should I enlarge my Ram memory to 256 GB?

Please advise.

    Hey Uri,

     

    Actually in installer we config .xml file, and there we need to increase the thrush hold value ,
    C:\Program Files\Altair\2019.4.2456\InspireCast2019.4.2456Dev\hwx\plugins\freedom\profiles\c2c\config\solverConfig.xml, (you can  change the setting in this file)
    <param txt='Max num of elements allowed for run' dv='20' id='max_allowed_num_elem_run'/>
    change the 20 value to your requirements.
     
    I have a question for you Uri: How did you calculate the RAM ? 
     
    Thanks

    Hi Uri,

     

    Thank for the answer, getting back to our previous conversation I would recommend you to increase the RAM , although running with 20 million elements is not that worth. Anyways is it possible for you to share the file? I can have a look at it. 

     

    Thanks

    Hello

     After changing Max num of elements allowed for run' dv='20' id='max_allowed_num_elem_run'/>  to 30

    it worked O.K.
