Default calculation with increased pressure

Dear all,

I am working on a chemical conversion problem with temperature and absolute pressure dependent chemistry, implemented in mainly posdat and some other routines. The code is working fine on ambient pressure. Now I tried to calculate on a higher absolute pressure level. I increased the pressure in the monitoring and reference data and in the liquid and gases initialization with "code initialization - include pressure". The results are not as I suspected, has anyone any idea if I forgot any changes or if I probably do need any switch?

Thanks for your help, nicola

Why did you change your reference pressure in monitoring and reference? That's only the pressure of reference, not the pressure in your simulation...real pressure is reference pressure plus relative calculated pressure. You can change the initial pressure simply by "init command", simply by: pmat,1,fluid (if it's material 1) cini,y,y,,0 (code pressure initialization) init,stan,u,v,w,sistem of reference,omega,p,keps,k,eps,T where you must substitute value such as init,stan,0,0,0,1,4000,50,keps,2.1,4000,293 Hope that works!
