Hi
I'm going to a non-Newtonian models for blood do I use the models caro and casson. When the models for the following phrases (in cfx expression language)and I'll solve the problem, not a correct answer that it review the resulting graphs can be realized. When the models in the software I use, firstly when entering model casson and begin to solve it is removed from the solver and Gives the following message. Do phrases are correctly expressed? And how do I use casson model?</SPAN></SPAN></SPAN> casson model in CELsqrt(tawy/abs(min(uppers,max(sstrnr,lowers))))+sqrt(miuc))^2 tawy:6.7253e-04[kg m^-1 s^-2] miuc:0.008[kg m^-1 s^-1] uppers:300[s^-1] lowers:0.00001[s^-1] caro model in CEL:miubin+((miuzero-miubin)*(1+(a*((min(uppers,max(sstrnr,lowers))) ^2)))^n) miubin:0.007888[kg m^-1 s^-1] miuzero:0.12805[kg m^-1 s^-1] uppers:300[s^-1] lowers:0.00001[s^-1] error in casson (Models in software): Details of error:- ---------------- Error detected by routine DELDIR CDRNAM = get_VISCDYN CRESLT = NONE Current Directory : /FLOW/SOLUTION/TSTEP0/CLOOP0/ZN1/VERTICES/GLOBAL/MINIMUM Details of error:- ---------------- Error detected by routine MAKDAT CDANAM = LVAR CDTYPE = INTR ISIZE = 77 CRESLT = OLD Current Directory : /FLOW/ALGORITHM/ZN1/SYSTEM/VARIABLES thank you very much |

thank you michael_owen
Please you are right. But when casson model in its software that I use the numbers assigned to give error messages tawy:6.7253e-04[kg m^-1 s^-2] miuc:0.008[kg m^-1 s^-1] uppers:300[s^-1] lowers:0.00001[s^-1] error in casson (Models in software): Details of error:- ---------------- Error detected by routine DELDIR CDRNAM = get_VISCDYN CRESLT = NONE Current Directory : /FLOW/SOLUTION/TSTEP0/CLOOP0/ZN1/VERTICES/GLOBAL/MINIMUM Details of error:- ---------------- Error detected by routine MAKDAT CDANAM = LVAR CDTYPE = INTR ISIZE = 77 CRESLT = OLD Current Directory : /FLOW/ALGORITHM/ZN1/SYSTEM/VARIABLES thank you very much |
