Dear Ian,

Sorry that I did not notice that I used a wrong directory. And after I corrected , it works!
Since I wanted to plot gravitational waveforms, I followed the steps in the Wolfram CDF file about gravitational waveforms. However I met a problem when I want to read ADM mass :

Since it is my first time to use Mathematica, I am not sure what this error message is about.
How should I set ProviderPreferences["InitialData"]?

Best regards,

Chia-Hui Lin

Dear Ian,

I followed the steps in this page:

http://simulationtools.org/Documentation/English/Tutorials/Introduction.html

I have installed both SimulationTools and h5mma into my home directory in Edison, but I cannot move it to ~/Library/Mathematica/Applications which seems to be a required step :

Hi,

The instructions say

SimulationTools is available as a tar.gz file containing the SimulationTools application directory. The SimulationTools directory should be placed in ~/Library/Mathematica/Applications on Mac OS, and ~/.Mathematica/Applications on Linux.

Since you are using Linux on Edison, you need to place it in ~/.Mathematica/Application, which is in your home directory.

There are equivalent download instructions at

http://simulationtools.org/download.shtml

which might clarify this.

By the way, I have installed NX,which is a computer program that handles remote X Window System connections to run Methematica. And I tried directly load SimulationTools (maybe there is SimulationTools already installed in Edison, or maybe I can load SimulationTools even it is located in my home directory) like below:

It failed, so SimulationTools seems to be required to move to Application directory of Mathematica.

Yes, that should fix the problem.

NX is good; that should be fast enough to use Mathematica remotely.

Good luck, and please keep asking questions if you need help!
