Dear All,

 

I am eager to reproduce the results in 1208.6577 and grateful for the assistance. I might recommend adding the installation of zlib to the “Compile opal on rhel6” page, somewhere before the compilation of opal.

I added zlib as required library.  

 

This caused the make command for opal to fail right before finishing. Also, I needed to change permissions of the /usr/local/, /usr/local/lib, and /usr/local/include to 777 and then back to 755 for the make install to complete copying some files around. Otherwise, it seems to be up and running. OPAL is a great help and I look forward to applying it.

 

Instead of changing permissions you can use “sudo” to make the installation,

Cantwell

Subject: Re: [Opal] Help with the multipacting simulation on OPAL

 

Hi Cantwell 

 

The multipacting mode is only available in OPAl 1.6. So after cloning the master,

change to the 1.6 tag with:

 

% git checkout OPAL-1.6

 

Chuang Wang in the cc can help you to get the parallel plate test running. This is 

First thing you should do, the results are documented in 1208.6577 . We are about 

to finalise this paper.

 

For running something like: multipacting.in, you would need to have a geometry. Also here Chuan is 

The right person to ask.

 

Cheers Andreas

Dear Cantwell, 

 

I haven't ever used the multipacting feature of opal and I don't know in what state the relevant code is. Unfortunately I also don't have the time to look into it in depth: I work for a funding agency and I can't work on opal during office hours. 

 

I hope Andreas and Achim can help you with your problem. 

 

Best, 

Christof

Dear Christof,

 

My name is Cantwell Carson and I am hoping you can help me.

 

We are making multipaction suppression coatings and I want to create the multipaction susceptibility zone maps for V vs GHz.mm. I would like to use OPAL but am having trouble compiling OPAL and running the multipacting.in demo. I have installed OPAL 1.6, but this is incompatible with the 1.9 code on master branch. I have been using a virtualbox and installing opal on SL7 and will try installing the opal nightly on a clean install. This would be the latest in several tries to get the multipacting.in simulation working, and I thought I would ask you for any advice that you might have. 

 

Could you help me get the multipacting.in simulation running on OPAL 1.9 on a clean installation of SL7?

 

Thanks!

 

Yours,

Cantwell
