We developed a new visualization approach to gain a better understanding of the displacement of one fluid phase by another in porous media. This is based on a recent experimental parameter study with varying capillary numbers and viscosity ratios. We analyse the temporal evolution of characteristic values in this two‐phase flow scenario and discuss how to directly compare experiments across different temporal scales. To enable spatio‐temporal analysis, we introduce a new abstract visual representation showing which paths through the porous medium were occupied and for how long. These transport networks allow to assess the impact of different acting forces and they are designed to yield expressive comparability and linking to the experimental parameter space both supported by additional visual cues. This joint work of porous media experts and visualization researchers yields new insights regarding two‐phase flow on the microscale, and our visualization approach contributes towards the overarching goal of the domain scientists to characterize porous media flow based on capillary numbers and viscosity ratios.

“…For the visualization of multiple domain boundaries, we used a two-sided material rendering technique (described in detail in Naumov et al (2014)) obtaining an unobscured view on the local fluid flow visualization simultaneously keeping the reference to the geometry. Figure 15 depicts the particle visualization with two-sided materials rendering.…”

Scientific visualization is an integral part of the modeling workflow, enabling researchers to understand complex or large data sets and simulation results. A highresolution stereoscopic virtual reality (VR) environment further enhances the possibilities of visualization. Such an environment also allows collaboration in work groups including people of different backgrounds and to present results of research projects to stakeholders or the public. The requirements for the computing equipment driving the VR environment demand specialized software applications which can be run in a parallel fashion on a set of interconnected machines. Another challenge is to devise a useful data workflow from source data sets onto the display system. Therefore, we develop software applications like the OpenGeoSys Data Explorer, custom data conversion tools for established visualization packages such as ParaView and Visualization Toolkit as well as presentation and interaction techniques for 3D applications like Unity. We demonstrate our workflow by presenting visualization results for case studies from a broad range of applications. An outlook on how visualization techniques can be deeply integrated into the simulation process is given and future technical improvements such as a simplified hardware setup are outlined.

“…The main target of information share-oriented and game-rooted systems is to develop virtual scenarios to attract the users, although the two systems differ in that the latter aims to provide convenient visual methods for data research, expression and understanding, while the latter aims to provide users with vivid scenarios that allow deep perceptions as well as fun. To satisfy the needs of both systems, much work has focused on the fields of scientific visualization of environmental systems and processes (e.g., Rink et al 2014a, b;Helbig et al 2014;Liu et al 2014;Naumov et al 2014) and Virtual Reality (VR) (e.g., Rauschert et al 2002;Wall and Brewster 2004;Jansson and Pedersen 2005;Bilke et al 2014). These efforts have greatly promoted the use of virtual environments to some extent.…”
