We present , a new numerical code to simulate the evolution of matter created in heavy-ion collisions presence electromagnetic fields. It is derived from Black Hole Accretion Code (), which has been designed model astrophysical processes general-relativistic magnetohydrodynamical description. As original Code, benefits use adaptive mesh refinement, allows us dynamically adjust resolution where necessary and makes time-dependent Milne coordinates ultrarelativistic equation state, <a:math xmlns:a="http://www.w3.org/1998/Math/MathML"><a:mrow><a:mi>P</a:mi><a:mo>=</a:mo><a:mi>e</a:mi><a:mo>/</a:mo><a:mn>3</a:mn></a:mrow></a:math>. demonstrate that accurately passes number systematic rigorous tests.
