Requesting help in simulating an ejector with refrigerant(R125) as the fluid using ANSYS Fluent

The errors that occur are: divergence, floating point exception, invalid cp, reversed flow, etc. but these are the most common

The solutions I have tried now are

In the Setup
- Changed discretization
- Changed from real-gas-NIST to polynomial
- Changed courant number and relaxation factor

In the mesh
- Changed element size from very fine to coarse
- Tried refining the throat area, tried other refinement methods

In the geometry
- Tried various different physical parameters that are allowed for the ejector study.

In the picture, only half of it is done as it is a 2D-axisymmetric instead
I also attached the allowed parameters

Please send help, I have been stuck on these for weeks now. I still cant get those shockwaves to form. Thank you!

Can simple conditions affect relative weaknesses in your cognitive profile?

To define simple conditions, it is only on controllable things like temperature, fatigue, time of the day, etc.

My relative weakness is VSI in which it is 1-2SD behind my other strengths. I only score 115-130 in this area depending on the type of subtest.

Now I am asking this because these simple conditions do not affect my strengths and relatively remain the same even at extreme fatigue. I have seen it in terms of my WMI.

Now for the context, I did WAIS-IV block design and visual puzzles. I scored 13 on each. The conditions at the time were: It was evening when I took the test, These were I think around 4th-6th in the sequence if subtests administered, and I was kinda shivering at this point due to temperature of the clinic.

The good things are I have complete sleep and I ate a light meal around 3PM.

Given these information, could I have probably scored more around my peak of 130 or would it have remained the same at 115?

Just interested in whether it can be affected or not so I can stop my copium in VSI ahahahaha.

Just took the WAIS-IV test and my score is similar to my CORE.

It was the same as I got 146 FSIQ on CORE and I got 146 on WAIS-IV. The same things are that my working memory and processing speed are the highest.(19,17 on DS and AR) (19,19 on CD and SS)

In the PRI section, it confirms that I truly only have above average-superior intelligence on VSI while genius level on FRI. It mostly affirms all the online tests I took.(13,13,18 on BD, VP, and MR)

My VCI is around the same as my CORE and even 1926 SAT so there is that. (15,15,16 on vocab,similarities, and information).

There truly are ceiling effects at some subtests then? Since I perfected MR but only got 18

I should have also not overthought that simple question on AR but there is that.

Overall a good test and affirms what I know about my own intelligence.

That last item on BD blanked my brain out haha. I wonder why I was not able to answer it.

Color blindness(Color deficiency) during Ishihara Test for MedCert means daytime driving only condition?

For context, kumuha ako medical certificate para sa renewal ko sa LTO this month since paexpire na license ko.

Nung kumuha ako medical cert, color deficient ako or color blind na rin since ayun yung mas common term pero nakikita ko pa rin naman kulay nung stoplight. Ngayon ang sabi sakin nung nag issue nung medcert ay bagong rule lang daw nung LTO yung ganito na kapag color blind meaning may condition na rin na for daytime driving nalang.

Ang tanong ko is pwede pa ba to mapatanggal or may magagawa pa bang paraan? Nakakapagdrive naman ako sa gabi matagal na since 2021 pa license ko at hindi naman ako nagkaproblema sa mga stoplight, brake lights, turn lights, etc.

I want to know if SB5 or WAIS-IV is better once I take an IQ test?

Basically, I will be taking a test soon, and I just want to know which is better. Are there downsides to choosing one over the other, or does it produce identical results for a score around the 140+ range? The 140+ is from CORE so it might not be representative of me.

I want to ask if there are centers in the Philippines that administer WAIS-IV as is like just for the purpose of taking an IQ test.

I am from the Philippines and want to ask if it is actually available in my country or not. If anyone knows, can you please tell me location and possible pricing?

Just took the web.archive.org 2013 JCTI IQ test. Is it true that it is deflated or is it my real score?

For context, I am asking as my scores on many websites indicate my FRI to be 135-140+.
On JCTI, I only hit 125(120-131) on my first try and after spending a bit of time again on the items(I know this can be due to practice effect or something), I finally hit the median of 133(127-138). I think that change can be due to some items that I have just not seen clearly on my first try, hahaha.

I took FRT-Type B(Would FRT-Type A have a difference?)from what I remember and just got the results back and it says 135, 99th percentile.

I am asking as I have seen and read that some Mensa IQ tests have ceilings such as 135, 145 and etc.

I have no problem having that IQ but if that is the ceiling then I would look for other administered IQ tests.

Edit: Did some research and it would suggest that 135 is indeed the cap. I digged and found the FRT-Type A with an answer key and scored around the same that I think I scored in Type B. I researched the resulting IQ scores for Type A and that getting the same score I did also results in a cap of 135.

Edit2: Just contacted the Mensa chapter here and confirmed that it is indeed capped at 135.
