Simulation of physics experiments at CERN (European Organization for Nuclear research) is underway in parallel of real experiment. There are strict requirements to reach the adequacy of data coming from detectors and event’s generator. In most of cases there are discrepancies and there are several options from where they might be come. Differences may be caused by geometric inaccurateness of models. So, development of methods and tools for creation of precise geometry models of ATLAS Detector is actual task. For this purpose special method so called “Simulation Loop” has been developed. Simulation Loop permits to carry out investigation of various geometries and discover existing inaccuracies. Investigation of model of COIL geometry was carried out using Simulation Loop. As a result volumetric and weight inaccuracies was found. Received results were considered by simulation group at CERN. As a result discrepancies were reduced.
