Hi Community,<\/p>\n

I am confused by the definition of the variable fvalmid <\/strong>in the subroutine uctrl1 <\/strong>from the umat dyn21.F<\/strong>. From the description found in the same file, fvalmid is an “array for predicting load curve values at time n+3\/2”, but what does n+3\/2 mean? <\/p>\n

Further to this, I am using uctrl1 to dynamically update the values of a curve, and assign this curve as a pressure boundary condition used in my ICFD simulation (this is due to the dyn21icfd.F has yet come to effect).  However, I am aware that the method does not currectly update the value to the curve (the pressure I wish to use @time n is different from the value in my .out file). Do you have any suggestions for me to implement to fix this issue?<\/p>\n

FYI, I am using R14.1.<\/p>\n

Thank you.<\/p>\n","protected":false},"template":"","class_list":["post-353821","topic","type-topic","status-closed","hentry","topic-tag-UMAT-1"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
