Yes, CONVERGE 3.0 can load a vof_spray.dat file that was written by an older version of CONVERGE as long as the Injector IDs and Nozzle IDs in the older files match the Injector Names and Nozzle Names in the 3.0 spray.in file. This feature may be useful for simulations with larger geometries, such as gas turbines. You can use values greater than 1.0, although higher values might affect solution stability or accuracy. The inlaid mesh is defined as part of the geometry and it belongs to the surface file; therefore, the inlaid mesh cannot intersect with any other boundaries of the geometry.

The Reaction multiplier option can be used to increase or decrease fuel burn rates (in CONVERGE Studio, go to Case Setup > Physical Models > Combustion modeling > Models (SAGE) > SAGE Parameters). Then, set up the correct boundary conditions for all surfaces belonging to the user-made mesh. The first cycle did not have this problem. How can I correct this?How can I calibrate the ignition delay in the Shell ignition model?Can the RIF model be used to simulate premixed combustion in CONVERGE?Does the RIF model require an autoignition model in order to simulate diesel combustion?Does CONVERGE use pre-compiled flamelet libraries (lookup tables) or does CONVERGE solve the kinetics in the mixture fraction space on the fly?Does the RIF model in CONVERGE support unsteady and multiple flamelets?Can I use the same mechanism for the SAGE detailed chemistry solver and the RIF model?What advantage do the simplified combustion models have compared to the SAGE detailed chemistry solver?Do the phenomenological, PM, and PSM soot models work with the RIF combustion model?Which species and reactions are considered in the CTC model?Which parameters should I change to calibrate the CTC model?How can I avoid having my soot values oscillate close to EVO?Can I predict engine knock using the G-Equation model?When using ECFM3Z, how can I generate my own TKI tables?How can I convert a map.out file from a SAGE simulation for use with an ECFM simulation?Can CONVERGE tune kinetic mechanisms to match ignition delay and laminar flamespeed data?Do I need a separate license to run CONVERGE’s chemistry tools?What are some aspects of the 0D reactor modeled in CONVERGE?Can the chemical equilibrium (CEQ) conditions be calculated via CONVERGE’s chemistry tools?What ignition delay (ID) definitions does CONVERGE use?Can I use chemistry tools to explore the flammability limits of a mixture?Can I use chemistry tools to create laminar flamespeed tables?Can CONVERGE reduce kinetic mechanisms while conforming to ignition delay and laminar flamespeed targets?Can CONVERGE tune kinetic mechanisms to match ignition delay and laminar flamespeed data?Can I use a chemistry tool to merge two chemical mechanisms?What film splash models are available for aftertreatment simulations?To predict deposit formation, should I use the molten solid approach or detailed urea decomposition?Can CONVERGE write out important spray statistics such as SMD or mass flux from a Lagrangian spray simulation?I am simulating a symmetric multi-hole injector, but the spray penetration patterns from each nozzle are not identical. For CONVERGE 3.0, the MPI packages are shipped with the installation package to reduce the likelihood of compatibility issues. This is a more robust method of determining steady-state convergence than simply looking at how much better the simulation is than where it started (i.e., residuals). Please be sure temporal_control > max_cfl_u in inputs.in is less than 1.0. Please consult the CONVERGE 2.4 Manual for recommended parameters for steady-state simulations. Conjugate heat transfer (CHT) is usually used for simulations with filming and Urea deposit formation. Single cell calculations without CFD boundary conditions For CONVERGE 3.0, the load balancing is performed with the parallel ParMETIS algorithm, and it is cell based.

On a Linux machine, this error may be the result of MPI interacting with an NFS-mounted file system. What is the problem?I am comparing heat transfer coefficients (HTCs) from CONVERGE with HTCs from other codes and they do not match. Why?There is burning in the intake port during the second cycle of my G-Equation simulation. Open the accompanying dialog box to specify the species-specific LHVs. This error is often related to an incorrect INTERFACE assignment. Join us online for the 2020 CONVERGE User Conference! CONVERGE 3.0 rarely load balances poorly. Can I use this feature to ensure I have an acceptable mesh near the wall for the law-of-the-wall models?How do the scalability improvements in CONVERGE 3.0 affect my simulations?Can I run cases with hundreds of millions of cells in CONVERGE on my HPC?Can I import my native CAD files directly into CONVERGE?What is the best way to extract aero-volume from a CAD geometry?How would having inlaid cells in my domain affect the load balancing in CONVERGE 3.0?Is there any difference between the way paired cells are shown in 3D post-processing of CONVERGE 3.0 and earlier simulation results?Why do I get different cell counts for similar CONVERGE 2.4 and 3.0 simulations?Can CONVERGE automatically match the cell sizes on a Cartesian-inlaid mesh interface?Can CONVERGE automatically improve the quality of the mesh in tight gaps?Are there any new types of AMR available in CONVERGE 3.0?What is an inlaid mesh? In CONVERGE Studio, go to Simulation Parameters > Run parameters > Misc and set the Screen print level to Verbose or More verbose. Please contact the Convergent Science Applications team [support@convergecfd.com (US), supportEU@convergecfd.com (EU), or support.in@convergecfd.com (India)] to obtain a script for this conversion. The format of the map file for CONVERGE 3.0 has changed to HDF5. This is the PIN provided by Converge or your merchant account provider. Is there a way to improve the results of my simulation?There is burning in the intake port in my G-Equation simulation. Please make sure with the Simulations Lead that no other critical sims are running before you start yours.
