Hello!

Request for your help.

I have read a lecture about the gas/particle two phase flow simulation, and it provided the q1 and ground.for file. What should I do to finish the simulation if I use the above q1 file and modified ground.for file.

Eager for your help!

Dear Zheh

Your question is so general that it is too difficult to answer (for me at least). Please be precise in what you want to know.

Nevertheless, to answer your questions I can tell you the following. If you are working in Windows try to use the "Task Manager" to finish your simulation; if you are working in Unix enviroment then you have more options but "top" could be a usefull program to manage your process.

Regards

Kike

Dear Kike:

Thank you for your acknowledgment.

My problem: (1).In Win98 system. (2).q1 and ground.for file in the following accessories. (3).How to continue the simulation if i use the above q1 and ground.for file(compile and link for instance). (4).thanks a lot in advance.

Accessories:

Dear Zheh

Before reading all this code lines, could you describe us your physical system?, What do you want to simulate?, What are the models you want to consider into the real physical system?

Could you tell us what are the problems you have with the executable?

Regards

Kike

Dear Kike:

Thank you for your acknowledgment, and i am so interested in the advice from you.

My aim is to simulate the flow behavior in a cold-flow pilot-scale circulating fluidized bed.

(1).The flow calculation is based on the two-phase gas/particle IPSA in PHOENICS,where the gas as well as the particle are considered as continuums.

(2).under 2 dimension Cartesian Coordinate system.

(3).The flow model is based on an Eulerian description of the phases and the conservation equations for the solid phase are derived from kinetic theory for granular flow.

I should tell you that i want to learn how to use PHOENICS, and the Q1 & ground.f file come from certain lecture. The two files has been copied to the appropriate place in VR-Editor of PHOENICS. What i want to konw is that how to finish the simulation using the above two files.

regards

Zheh

Dear Zheh (or Adler)

I have seen (from your questions) you should read once again the information you have with your PHOENICS version and if it is lost (or something else) you can read some details at www.cham.co.uk

I wouldn't like to be misunderstood. I want to help you, but, as far as my experience can tell me, you will need more than a few answers here.

Unfortunately I haven't any experience with the last versions of VR-Editor, but I will suppose you have put the codes in the righ place into the Editor, because you have read the manuals.

(a) If I assume the VR has no changed from version 3.1 (the las I have used) and (b) if you are working from the PC (PHOENICS Commander), then, you can "exit" from the VR-Editor (see the button in the right botton corner). You should see the message: "EARDAT file written". It means that PHOENICS is ready to compute your case.

The VRE windows disappears and you can click on "Earth" button in PC. If everything has been OK then you will see a graphical interface or a text window in which PHOENICS will print some output messages and data.

Lets the code finish the calculations (the windows I mentioned will desappear) and click the VR-Viewer button in PC.

You will see another window where the results of your simulation can be seen. Now, if you want to know the details about how the VR-Viewer works you have two ways to continue: (a) click the buttons to see "what happen" or read the VR-Viewer user manual. Sincerely, I think it is too hard to explain here and you should not forget that today is sunday.

Please, try to avoid what I am doing now. Don't work at sunday, go for a walk with your friends or family. Have a nice day

Regards

Kike
