I am building a PC specifically for my CFD project. Has anyone experienced any kind of bugs while using it on Ryzen processors?
Specially-AMD Ryzen 5 2400G with Radeon RX Vega 11 Graphics
If anyone has an ANSYS 18.2 software on PC based on Ryzen processors please send the configuration.

Why would you use the VEGA 11 GPU? It doesn't have professional drivers of a Quadro or Radeon Pro. It's also very weak , on par with the GT 1030 or RX550 when DDR4 memory bandwidth isn't taken into account.
Since it's an integrated GPU solution you're going to have a rough time. In today's RAM pricing environment you'd be foolish to buy more expensive fast RAM when you can get a decent Quadro solution for around $300 (P1000 supports Discovery Live as well and is as powerful as a prior gen M2000).
If you do go with a Ryzen system and aren't going to utilize CUDA (Nvidia GPU) for any form of rendering or calculation, a Ryzen 7 1700 overclocked to 3.8GHz+ would work alright or at least a 6 core Ryzen 5 1600. If you aren't going to overclock then you're better off with Intel i5s or i7s , if not i9s.
P.S. I own a Ryzen 7.
If you're trying to be on a tight budget (meaning high core count X399 AMD Threadripper / X99 Haswell-E or Broadwell-E / X299 Skylake-X are out of the question) I would go with something as follows:
Intel system: i7-8700k overclocked, i7-8700 , i5-8600, i5-8500 , i5-8400 , or i5-8600K overclocked ; 8GB x 2 DDR4 or 16GB x 2 DDR4 (2666MHz or above); Quadro P1000 or used M2000
AMD system: Ryzen 5 1600 overclocked or a Ryzen 5 1600X ; 8GB x 2 DDR4 or 16GB DDR4 (2933MHz or above due to Infinity Fabric scaling); Quadro P1000 or used M2000
* Ryzen+ is coming April 19 with higher clockspeeds and memory compatibility improvements
P.S. ANSYS is adamantly using CUDA instead of OpenCL so don't expect to see top performance on Radeon Pro even if it is "supported". Its quite obvious that they are biased towards Nvidia , but can't blame them when Nvidia owns 70% market share.
