<p>As we discussed, EXSIE is called at every cycle for every element. Thus, in EXSIE you need to<\/p><\/p>\n

    \n
  1. Get the X\/Y\/Z of the element based upon the element index (INOW, JNOW, KNOW or IJKNOW),<\/li>\n
  2. Read this 800,000 lines files, locate the lines based upon the X\/Y\/Z from #1 and obtain their corresponding energy.<\/li>\n
  3. Calculate the deposited energy by interpolating the energy from #2. <\/li>\n<\/ol>\n

    <p>Since the program has to read the 800000 line file at every cycle and every element, this may take additional CPU time.<\/p><p>If you can simplify the energy distribution by an analytical expression of X\/Y\/Z coordinates, you can calculate the deposited energy with the equation, rather than read 800000 lines for every element, that will save running time significantly.<\/p><p>The density and pressure will be calculated by the subroutines that are corresponding to the EOS. For example, if Ideal-Gas EOS is used, density and pressure will be calculated in the subroutine of Ideal Gas EOS. <\/p><p>If you want to customize the density & pressure calculation, you need to edit the user-subroutine mdeos_user_1.f90. You may not need to edit the EXSIE. You can deposit the energy in the mdeos_user_1.f90.<\/p><\/p>\n","protected":false},"template":"","class_list":["post-359617","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/359617","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/reply"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/359617\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=359617"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
