<span style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">I would like to perform numerical simulations for a BH binary merger around a scalar cloud with EinsteinToolkit.
From now, I have been able to simulate the example of the TOV star given in the EinteinToolkit official page in my laptop and soon I will gain access to a computer cluster where I hopefully will be able to install the Toolkit and perform a simulation for the
example of a binary merger. But my aim is to be able to perform, maybe in its simplest version, a simulation of a merger around a scalar field, extracting information about both the evolution of the BHs and the scalar field itself.</span></div>

<span style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">The problem I face is that I am not sure at all if I will be able to do it without any parameter file. As far as
I understood, my current version of the Toolkit already has installed thorns related with the implementation of a scalar field (if I am not mistaken, one example is ScalarBase). I thus send this email asking if it is possible to obtain a parameter file for
simulating this scenario, or to provide me with any information about an existing tutorial on how to write one. Something like this would help me
<i>a lot. </i>I would appreciate any answer.</span></div>
